Answer 2

Given,

The speed of train = 80 km/h

To find,

The train will take how much time to cover a distance of 15 km.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

The train,

Covers 80 km in = 1 hour

Covers 80000m in = 3600 seconds

Covers 1m in = 3600/80000 seconds

Covers 15km or 15000m in = (3600×15000)/80000 = 675 seconds

Total time taken = 675 seconds = 660 seconds + 15 seconds = 11 minutes 15 seconds [As, 1 min = 60 seconds, 11 minutes = 660 seconds.]

Hence, the train taken 11 minutes 15 seconds to cover the distance of 15 km.
