Question

3) A man runs 2.5 km in 10 min. Find his speed in
km/h.​

Answer 1

The man runs in 10 mins =2.5km

Therefore,

$1hr = 60 \: min$

$so \: \: 2.5 \times 60 = 150km \: per \: hr$

Answer 2

Your answer is 250 km/h

We need to apply the formula for finding speed :

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

$speed = \frac{2.5}{10}$

$speed = 0.25m$

Now we need to find the speed in km/h

So,

We know that 1 Kilometre=1000 metre

Now we will multiply 1000 with 0.25

$1000 \times 0.25$

$250$

So your Answer is 250 km/h....
