The tire of a car traveling

Question

The tire of a car traveling at a speed of 60 miles per hour rotates 269 times in 20 seconds. If the car continues to travel at the same speed, which of the following is the number of times in 20 seconds. If the car continues to travel at the same speed, which of the following is the number of times the tire will rotate in 1 hour?

Answer 1

1 minute = 60 seconds.

If the tire rotates 269 times in 20 seconds, then in 3 x 20 = 60 seconds = 1 minute the tire will rotate 269 x 3 = 807 times.

There are 60 minutes in an hour. Since the tire rotates 807 times per minute, it will rotate 807 x 60 times in 60 minutes = 1 hour.

807 x 60 = 48,420 rotations.
