**Reiny**, Wednesday, June 16, 2010 at 8:48amLet the time taken by the bus for the trip be t hours

Let the time taken by the car for the trip be t+1.5

distance covered by bus = 60t

distance covered by car = 40(t+1.5)

60t = 40(t+1.5)

60t = 40t + 60

20t = 60

t = 3

bus goes for 3 hours and the car for 4.5 hours

check:

3x60 = 180

4.5x40 = 180
