Answer 2

Hi mate,

Here is your answer,

Given, Distance if the bus = 50 km

Time= 45 min.

We know that,

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

$speed = \frac{50}{45}$

$speed = 1.11..... \infty \: kmpm$

Now we have to find the speed in m/s

we know that,

$1km = 1000m$
then
$50km = 50000m$
we know that

$1min = 60sec$

then

$45min = 2700sec$
No we find the speed in m/s

18.51m/s is the final answer.

At least the answer is complete


HOPE THIS IS HELPFUL FOR YOU
