Question

a car cover 3km in 5min calculate its speex in m/s and km/h

Answer 1

Hi mate


Here is your answer

Given, Distance=3km

Time = 5min


First we find the speed in mps


We know that



$1km = 1000m$
Then

$3km = 3000m$

We know that

$1min = 60sec$
then

$5min =300sec$


We know that


$speed = \frac{distnce}{time}$

$speed = \frac{3000}{300}$

$speed = 10mps$


Now we have find the speed in km/h


we use the direct formula


$speed = 10 \times \frac{18}{5} kmph$


$speed = 36kmph$


HOPE THIS IS HELPFUL FOR YOU

Answer 2

given,distance=3km=3000m

time=5min=300sec

speed=distance/time

=3000/300

=10m/s

speed=10*18/5km/h

=36km/h
