Questions =>A train covers {404}/{5} km in 1 hour. How much distance will it cover in {19}/{4} hours?

ANSWER

Now, given

In 1 hour train covers = 404/5 km

Or

In 60 min the train covers = 404/5 km.

Now, Remember =>>

1 hour = 60 minutes

1km= 1000 metres.

Now,

19/4 hour = (19/4 )×60 = 19×15

= 285 minutes

So, according to the question

By using UNITARY METHOD =>

In 60 min the train covers = 404/5 km.

In 285 min the train covers

=(404 /5×60)×285

=(404/300)×285

=383.8 km

So the train covers 383.8km distance in {19}/{4} hours or 285 minutes.
