Mathematics Question on Time Speed and Distance
A train can travel 20% faster than a car. Both start from the point A at the same time and reach point B 75 km 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
50 kmph
B
55 kmph
C
60 kmph
D
65 kmph
Answer
60 kmph
Explanation
Solution
The correct option is (C): 60 kmph
Explanation: Let speed of car = 10x km/hr
Speed of train = 12x km/hr
Time taken by both to travel 75 km =75/ 10x = 75/12x + 12.5/60
75/60x=12.5/60
x=75/12.5=6
So speed of car =60km/h
