# A train after every 82.5 km. takes rest for 3 min moving at a faster s

| A train after every 82.5 km. takes rest for 3 min moving at a faster speed of 110 km/hr whereas another train takes rest for 1 min. after every 27.5 km. moving at slower speed of 55 km/hr When faster train covers 660 km. then find what is distance covered by slower train?

A. 572 km

B. 506 km

C. 357.5 km

D. 338.25 km

### Right Answer is: D

#### SOLUTION

Time taken by faster train to cover 660 km = = 6 hr. = 360 minutes

No. of stoppages = = (8-1) = 7 (last stoppage will not be counted)

Time in stoppages = = 21 minutes

Total time taken by faster train = 360 + 21 = 381 minutes

Time taken by slower train to cover 27.5 km = = 30 minutes

Total time taken by slower train to cover 27.5 km = 31 + 1 = 31 minutes

30 minutes 27.5 km

9 minutes = 8.25 km

So, the slower train will cover 338.25 km.
