Q:
The difference between the time taken by two trains to travel a distance of 350 km is 2 hours 20 minutes. If the difference between their speeds is 5 km/hr, what is the speed of faster train ?
Answer & Explanation
Answer: B) 30 kmph
Explanation: Let the speed of the faster train be 'S' kmph
Then speed of the slower train will be '(S-5)' kmph
Time taken by faster train = 350/S hrs
Time taken by slower train = 350/(S-5) hrs
=> S = 30 km/hr.
