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:
- 100 kmph
- 110 kmph
- 120 kmph
- 130 kmph
Let the speed of car be x kmph.
Therefore, the speed of train = 1.5x kmph
Distance traveled by train and car is same. Time difference is 12.5 minutes.
(75/x) - (75/1.5x) = (125/10x60)
x = 120
The correct option is C.
