Speed is given in 'miles per hour'. The word per just means 'each' or 'every', so we could just a s well say 'miles each hour' or 'miles every hour'.
So, basically the car has travelled 660 miles in 11 hours so we have to find how many miles it travels in just one hour.
To get the answer we divide the total number of miles (660) by the total number of hours (11). The calculation is 660 divided by 11 and the answer is 60 miles per hour.
Hope this helps.
We can solve this problem using the concept of speed. We know the speed: The information states that it takes 2 hours to travel 90 miles. Therefore, the speed is 90 miles / 2 hours = 45 miles per hour. Now, we need to find the distance with a different travel time: You want to know how far you can travel in 7 hours with the same speed of 45 miles per hour. Use the formula: Distance = Speed × Time Plug in the known values: Distance = 45 miles per hour × 7 hours = 315 miles Therefore, if it takes 2 hours to travel 90 miles at a constant speed of 45 miles per hour, you can travel 315 miles in 7 hours with the same speed.
The number of hours it takes is39.2/your speed, in miles per hour .
The number of hours it takes is1,230/(your speed in miles per hour)
If you are traveling 70 miles per hour, you will cover 70 miles in one hour.
How long it takes to go 140 miles depends on your speed. If you are in an airplane going 560 miles an hour, it takes 15 minutes. If you are on a fast train in China going 280 miles an hour it takes 30 minutes. If you are on a fast train in France going 140 miles an hour it takes 1 hour. If you are on an interstate highway going 70 miles an hour, it takes 2 hours. If you are driving on a two lane road averaging 35 miles an hour it takes 4 hours. And if your are in New York traffic and dodging pot holes while averaging 17 1/2 miles an hour it takes 8 hours.
The idea is to divide the distance by the speed. The answer will be in hours.
It takes (68 hours) divided by (the speed you travel, in miles per hour).
The time it takes will depend on your average speed while traveling. In hours, it will be (490/speed in miles per hour).
1/18
That takes 8 hours.
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
