Question

a train takes 3 hours to reach from station A to station B at a distance of 400 km and 5 hours in it its return journey . Find the average speed of the train​

Answer 1

Answer:

average speed = total distance/ total time

= 800/ 8 km/hrs

= 100 km/ hrs

Answer 2

Answer:

The correct answer will be -

The average speed of the train will be 100 km/h.

Explanation:

Given in the question  -

• A train takes 3 hours to reach from Station A to station B
• The Distance between station A and station B is 400 km.
• Train returns in 5 hours

We have to find the average speed.

We know that average speed is the total distance covered by the total time taken.

The average speed of any object is the total distance covered by the object in a particular time interval. This is a scalar quantity.

average speed  = $\frac{total\ distance \ covered}{total \ time\ taken}$

$= \frac{400+400}{3+5} =\frac{800}8} = 100\ km/h$

So, the average speed of the train will be 100 km/h.
