Question

A train takes 3 hours to reach from station A to Station B at the distance 500km And 7 hours in its returns journey that is from B to A .
Find the average Speed of the train
​

Answer 1

Answer:

speed= distance/time

= 400/5

= 80km/hr

velocity = displacement /time

= 0/5

= 0

Explanation:

Answer 2

Answer:-

• The average speed is -25 km/h.

Step-by-step explanation:

Given:-

• Total distance = (500 + 500) km = 1000 km
• Time taken = A + B = 3 - 7 = -4 hr

To find:-

• Average speed = ?

Solution:-

As we know that,

• Average speed = total distance/time taken

Applying the values,

$\\ :\implies\sf{Average\;speed=\frac{1000\;km}{3 - 7 hr}}\\ \\:\implies\sf{Average\;speed=\frac{\cancel{100}\;km}{\cancel{-4}\;hr}} \\ \\:\implies\sf{Average\;speed=-25\frac{km}{hr}}$

• ∴,the average speed is -25 km/hr.
