Wo trains leave the station at the same time going in opposite directions One of the trains travels at 90 mph and the other is traveling at 120 mph After how many hours will they be 735 miles apart?
Going in opposite directions, they separate at the rate of (90 + 120) = 210 miles per hour.They are 735 miles apart after (735/210) = 3.5 hours.
Marsha and Michael start at the same point and travel in opposite directions Marsha drives 63 mph and Michael drives 72 mph How far apart will they be in 3 hours?
... this is easy :l you need to do your own homework but I'll help :l 63 mph x 3 hours = ? 189 Miles Traveled 72 mph x 3 hours = ? 216 Miles Traveled They are traveling opposite directions so you add them together. 189 Miles + 216 Miles = ? 405 Miles Apart.
Two cars leave the gas station in opposite directions one is traveling 50miles per hour and the other is traveling 45miles per hour how many hours will they be 380 miles apart?
If they are traveling in opposite directions, then they are traveling away from each other at a speed of 95 miles per hour. 380/95=4 They have been traveling for four hours.

Two people leave simultaneously from the same starting point biking in opposite directions Linda bikes at 7 mph and Dave bikes at 9 mph how long will it be until they are 24 miles apart?
After 1 hour, Linda will be 7 miles from the starting point, and Dave will be 9 miles away from that point but in the opposite direction. So they will be exactly (9+7=) 16 miles apart after 1 hour. They are moving apart at a rate of 16 mph. After 1.5 hours they will be exactly 24 miles apart.
A Canada goose and a Great Blue Heron took off in opposite directions The goose flew at 20 mph and the heron flew at 10 mph When they landed they were 180 miles apart Altogether they flew for 14?
4 hours (goose) and 10 hours (heron)
If Two cyclist start from the same point and ride in opposite directions One cyclist rides twice as fast as the other In 3 hours they are 81 miles apart What is the rate of each cyclist?
9 mph and 18 mph
Two boats leave from the same dock traveling in opposite directions The first boat is traveling 25 mph and the second is traveling 29 mph How long will it take before they are 162 miles apart?
To calculate the time it takes for the two boats to be 162 miles apart, you can use the formula: time = distance / relative speed. The relative speed of the two boats is the sum of their speeds, which is 25 mph + 29 mph = 54 mph. Then, time = 162 miles / 54 mph = 3 hours. So, it will take 3 hours for the two boats to be 162 miles apart.
Linda bikes at 7 miles per hour and Dave bikes at 10 miles per hour how long will it be until they are 23 miles apart?
There isn't enough information to give you a definitive answer. We also need to know in which direction they are riding. If they are both riding in a straight line in the same direction, they will be 3 miles apart at the end of the first hour, 6 miles apart at the end of the second our, and 23 miles apart at the end of 7 hours and 40 minutes. If they are both riding in a straight line in opposite directions, they will be 17 miles apart after the first hour, and 23 miles apart after 1 hour, 21 minutes, and 10.6 seconds.
Theres two trains leaving at the same time one going 60 miles per hour one going 50 miles per hour in 90 minutes how far apart will they be?
The distance travelled by each train is equal to its speed in miles per hour multiplied by the time travelled in hours. Since there are 60 minutes per hour, 90 minutes = 90/60 = 1.5 hours. Since no directions are given, presumably the trains are traveling in the same direction or in opposite directions. The distance between the trains will be 1.5(60 - 50) if the trains are traveling in the same direction and 1.5(60 + 50) if the trains are traveling in opposite directions. These values are 15 miles and 165 miles respectively.
If 2 cars start 100 miles apart drive in a straight line in opposite directions 1 is going 60 mph and 1 is going 45 mph when will they collide?
Never, since they are travelling in opposite directions.. . . but probably not the one the algebra book's authors intended....If you assume that "opposite directions" means the cars are travelling towards each other, their closing speed (i.e. relative speed) is 105 mph. That means they'll meet in 100/105 hours, or slightly more than 57 minutes.
If one plane flies directly at 540 mph and the other flies 720 mph how long will it take them to be 1890 miles apart?
depends on the direction of the planes if they are going in opposite directions it will take one and a half hours. If they are going in the same direction, it will take ten and a half hours This assumes they fly in a straight line
