I need asap solution

Hi there,

Come on. I believe you can answer that by yourself. You just need to apply the accelerated linear motion equations and you get to your answer

can u provide that linear accelerated motion...

 

[fatra2]

Not really, but I can help you find them.

Acceleration is define as a variation of speed: a = \frac{v_1 - v_0}{t}

In the case of accelerated linear motion, the average speed is equal to the mean speed: \overline{v} = \frac{v_0 + v_1}{2}

From these three equations, you have the solution to your question.

Hi shahzadzai!

They are the standard https://www.physicsforums.com/library.php?do=view_item&itemid=204" equations … see the PF Library.
