A car and a bus set out at 2pm fromthe same location and are headed in the same direction. after 2 hours, the car is 20 miles ahead of the bus.

Question

The bus is traveling at 45 mph... Please find the rate of the car and provide an explanation.

Answer 1

Zakiya.

 

Bus:  r = 45 m/h, t = 2 h,  d = rt, therefore, the bus travels 90 miles in 2 hours.

 

Car:  let its rate = r, time = 2 h,  d = 20 miles more than bus (90 miles + 20 miles) = 110 miles.

 

So:  r = 110/2 = 55 mph.

 

I hope this helps.
