Asked by Kyle Jackson

A car travels 315 miles in the same amount of time that a bus travels 245 miles. The rate of the car is 10 mph faster than the bus. Find the rate of the bus
Answered by Steve
since times are equal, and time = distance/speed

315/(b+10) = 245/b
b = 35

bus = 35 mph
car = 45 mph
check:

315/45 = 7
245/35 = 7
