Question

An object is moving at a speed of 63 centimeters every 2 days. Express this

Answer 1

Given :

Distance covered by object , D = 63 cm .

Time taken to cover distance D , t = 2 days .

To Find :

The speed of object in m/s .

Solution :

First we will convert all units into m and hours .

D = 63 cm = 0.63 m .

$t=2\ days =2\times 24\ hours =48\ hours$ .

Now , speed is :

$s=\dfrac{D}{t}\\\\s=\dfrac{0.63}{48}\ m/hours\\\\s=0.013\ m/hours$

Hence , this is the required solution .
