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

• math -

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
