# Find Its Usual Time to Cover The Journey.

Moving 6/7 of its usual speed a train is 10 min late. Find its usual time to cover the journey.

- 25 min
- 15 min
- 35 min
- 60 min

**Answer: (4) 60 min**

**Explanation:-**

New speed = 6 usual speed /7

Then, New time = 7 usual time /6

Therefore, (7 usual time /6 – usual time ) = 10 min

7 usual time – 6 usual time = 10 x 60

= 60 min

Hence, the answer is (4) 60 min.
