Question

A car travels 360 miles in a period of 180 minutes. Find the average velocity of the car in miles per hour over this time period.

Answer 1

You put 360 over 180.
This gives you 360 miles / 180 minutes.
Then change 180 minutes into hours which is 3 hours
360 miles/ 3 hours.
Finally reduce both top and bottom by three which gives you 120 miles per hour

Answer 2

The simple formula for velocity is v=d/t. Velocity equals distance divided by time. 360 miles divided by 180 minutes. 360/180=2. The car travels at 2 miles per MINUTE.

Now, to change to miles per HOUR. There are 60 minutes in an hour, so 2*60=120 miles per hour.

Answer: 120 mph
