A car travels 55 miles per hour and a plane travels 15 miles

A car travels 55 miles per hour and a plane travels 15 miles per minute. How far does the car travel when the plane travels 500 miles?

Solution

travel time of the plane = 500/15 = 100/3 minutes = (100/3)/60 hours = (100/180) hours = 5/9 hours
so the car will travel: 55*5/9 miles = 275/9 miles = 30.56 miles
