Q:
A) 15 kms | B) 9 kms |
C) 6 kms | D) 18 kms |
Answer: B) 9 kms
Explanation:
Explanation:
The first train covers 180 kms in 5 hrs
=> Speed = 180/5 = 36 kmph
Now the second train covers the same distance in 1 hour less than the first train => 4 hrs
=> Speed of the second train = 180/4 = 45 kmph
Now, required difference in distance in 1 hour = 45 - 36 = 9 kms.
