Question

if a body travel half of distance with the speed 30m/s and for remain half distance it travel with the speed of 5m/s​

Answer 1

Explanation:

In order to find out the average speed,

Just apply the formula for average speed.

i.e. 2xy/x+y (THIS FORMULA ONLY WORKS WHEN THE DISTANCES ARE EQUAL)

Therefore, applying the values,

2 × 30 × 5/ 30 + 5

=> 300/35

=> 60/7 or 8.57m/s
