Answer:
3 1/3 hours or 3 hours and 20 minutes
Solution:
distance = velocity x time
the distance travelled by the first cyclist = 15 x time
the distance travelled by the second cyclist = 12 x time
the difference distance = 15 x time - 12 x time
this difference will be 10 miles when
15 x time - 12 x time = 10
3 x time = 10
time = 10/3 = 3 1/3 hours
= 3 hours and 20 minutes.

How long will it take them to be 650 miles apart... someone plz answer now
two cyclists start at the same time from opposite ends of the course that is 51 miles apart. one is pedaling at 16 mph and the other at 18 mph, and when will the meet?
They are moving apart at 70 miles per hour - 30 plus 40. Therefore, in 3 hours they will be 210 miles apart.
Two cyclists are traveling the same path. The first cyclist stops every 11 minutes to take a drink. The second cyclist stops every 15 minutes to take a drink. If the cyclists continue to stop at the same rate, after how many minutes will the cyclists be stopped at the same rate?

The difference between the two speeds. So if one car is traveling at 60mph and the other is 70mph, it would be a 10mph difference since they are traveling in the same direction. Now, if they were colliding head on, it would be 130mph total speed.Also, 2 cars traveling at exactly the same speed and direction (assuming they start a certain distance apart) will never collide and will maintain that exact distance they started apart.

Two cyclists start biking from a trail's start 3 hours apart. The second cyclist travels at 10 miles per hour and starts 3 hours after the first cyclist who is traveling at 6 miles per hour. How much time will pass before the second cyclist catches up with the first from the time the second cyclist started biking? A. 2 hoursB. 4 ½ hoursC. 5 ¾ hoursD. 6 hoursE. 7 ½ hours AnswerThe distance the 1st cyclist travels is 6(3+t) miles, andthe distance the 2nd cyclist travles is 10t miles...where t=the number of hours since cyclist #2 starts.Now solve: 6(3+t)=10t ==> 18+6t=10t ==> 18=4t ==> t=4.5 hrs==> 4.5 hours = 4 hrs 30 minutes

Are they travelling on the same road? In the same direction? Which car is in front? How far apart were they to start with? Is the driver in the faster car blind?
We'll assume they start out at the same time, although the question doesn't say that.Kim's lead over Alex grows at (12 - 8) = 4 mph.After 6 hours, they're (6 x 4) = 24 miles apart.
