Step-by-step explanation:
It is given by :
..... (1)
Where
s = distance covered
a = acceleration of an object
t = time taken
We need to manipulate given equation to find the value of t. On cross multiplication to both side of equation (1) we get:

Dividing both side of above equation by a we get :

Taking square root of above equation we get :

So, the value of t is,
. Hence, this is the required solution.
