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
Serggg [28]
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.
