Question

A car travels 4km in three minutes find the speed car in cm/s

Answer 1

Time = 3 mins = 180 secs.

Distance 4 km = 4 × 100000 = 400000 cm.

Speed = V = ?

V = d/t

V = 400000cm/180 secs

V = 2222.22cm/s

$hope \: it \: helps \: you.$

Answer 2

given ,t =3min=3*60=180sec.....1
distance =4km=4*1000=4000....2
so by the formula of velocity =distance /time
we get , from 1and2
v=d/t
4000/180
v=2222.22
