A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75kms away from A at the same time . On the way , however , the train lost about 5 minutes while stopping at the station . The speed of the car is :  

A    100Kmph

B    110Kmph

C    120Kmph

D    130Kmph

Solution

Correct Answer: Option C

 

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
