Question

A train travel 650 kilometer in 5 hours how long will it take to travel 975 km

Answer 1

Step-by-step explanation:

it is by unitary method

first

time taken to complete 650 km = 5 h

time taken to complete 1 km = 5/650 h

Time taken to complete 975 km = 5/650 *975

= 7.5 h

Answer 2

Answer:-

Given:-

Train travels 650 km in 5h.

To Find:-

Time it will take to cover 975 km.

_____________...

It is a case of direct variation since more the train will cover distance, the more it will take time.

➤ x/y = k (constant)

and, x ∝ y

Let it will take = (t) hours to complete the journey.

So,

x/y = k

➠ (650)/(5) = (975 km)/(t)

➠ 975 km/t = 130

➠ 130t = 975

➠ t = 975/130

➠ t = 7.5

So, it will take 7.5 hours to complete the journey of 975 km.
