Question

if a man runs at 3.7 metres per second, how many kilometers, does he run in 1 hour 30 minutes?

Answer 1

Given that a man runs at 3.7 metres per second.

We have to find distance in 1 hour 30 minutes so let's convert 1 hour 30 minute into seconds

we know that 1 hour = 60 minutes

we know that 1 minute = 60 seconds

so 1 hour 30 minutes = 60 minutes + 30 minutes = 90 minutes = 90*60 seconds = 5400 seconds.

man runs 3.7 metres into 1 seconds then

distance in 5400 seconds = 3.7 * 5400 = 19980 metres.

But we need answer in kilometer so we divide 19980 metres by 1000

because 1 km = 1000 metre.

Hence final answer is 19980/1000 km or 19.98 km

Answer 2

Given a man runs 3.7 m in 1 second.

We are asked to find the distance travelled in 1 hour 30 minutes (5400 seconds).

Distance travelled = 5400*3.7 = 19980 m.

The distance we got is in meters but it is asked in kilometers.

So,19980 m = 19.98 km.

Therefore, the man can run 19.98 km in 1 hour 30 minutes.
