Answer 2

$\blue{\large\underline{\underline\mathtt{Question:}}}$

A man covers a distance with speed $\mathtt{v_{1}}$ and $\mathtt{v_{2}}$

for two equal time period. Find the average speed of the man.

$\blue{\large\underline{\underline\mathtt{Solution:}}}$

Let the time in both the cases be x.

[$\because$ It is given that the time period is equal in both thr cases.]

$\underline\mathtt{We\:know}$

$\red{\boxed{\rightarrow Average\:speed = \dfrac{Total\:distance}{Total\:time}}}$

Given,

• $\mathtt{distance = v_{1} and v_{2}}$
• $\mathtt{time = x}$

Putting the value in the Formula ,we get:-

$Rightarrow Average\:speed = \dfrac{v_{1} + v_{2}}{x + x}$

$\Rightarrow Average\:speed = \dfrac{v_{1} + v_{2}}{2x}$

$\green{\boxed{\mathtt{\therefore Average\:speed = \dfrac{v_{1} + v_{2}}{2x}}}}$
