Ahmed is moving with a velocity of `120 km//h`. How much distance will he cover (a) in one minute and (b) in one second ?

Answer

`750 m` ; `12.5 m`

Explanation

Here , `v = 45 km//h = ( 45 xx 1000 m)/( 60 xx 60s) = 12.5 m//s`
(a) ` s_(1) = v xx t_(1) = 12.5 xx 60 = 750 m`
(b) ` s_(2) = v xx t_(2) = 12.5 xx 1 = 12.5 m`
