Question

A body covers the first half of the distance between two places at a speed of 40m/s and the second half at 30m/s averave speed of body during whole journey will be​

Answer 1

Answer:

Average speed = 35m/s.

Explanation:

Given Information -

[assuming initial position as 'A' and final position as 'B']

• Speed from A to B= 40m/s
• Speed from B to A = 30m/s

To Find -

• Average speed.

Answer -

Average speed refers to sum of speeds per time taken.

Mathematically- $\frac{total\:distance}{total\:time\:taken}$

• $= \frac{40 + 30}{2}$

• $= \frac{70}{2}$

• $\bold\red{35m/s}$

So, Average speed is 35m/s.
