Question 262995: A car travels a certain distance taking 7 hrs in forward journey, during the return journey increased speed 12km/hr takes the times 5 hrs. What is the distance travelled
(a) 210 kms (b) 30 kms (c) 20 kms (d) none of these
You can put this solution on YOUR website! Let the speed of the forward journey = x kmph
Time taken for the forward journey = 7 hrs
The speed of the return journey = x+12 kmph
Time taken for the forward journey = 5 hrs
The distance travelled in both ways are equal.
7x = 5(x+12)
7x = 5x+60
7x-5x = 60
2x = 60
x = 60/2 = 30 kmph
The distance travelled = 7x = 7*30 = 210 kms
