A super cruiser bus leaves miami travelling at an average rate of 40 miles per hour.3 hours later a car leaves miami from san francisco travelling on the same route at 55 miles per hour.how long does it take for the car to over take the bus
-------
Bus DATA:
rate = 40 mph ; time = x hrs ; distance = 40x miles
------
Car DATA:
rate = 55 mph ; time = x-3 hrs ; distance = 55(x-3)miles
------
Equation:
dist = dist
40x = 55x - 155
15x = 155
x = 10 1/3 hrs = 10 hrs 20 min
Car time:: x -3 = 7 hrs 20 min
