A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:

A. 100 kmph B. 110 kmph
C. 120 kmph D. 130 kmph

Answer: Option C

Explanation:

Let speed of the car be x kmph.

Then, speed of the train = 150 x = 3 x kmph.
100 2

 

75 - 75 = 125
x (3/2)x 10 x 60

 

75 - 50 = 5
x x 24

 

 x = 25 x24 = 120 kmph.
5
