Question

a person covers 90 km in 2 hours 30 mins. what is it in m/s?

Answer 1

Answer:

10 metres per second is the speed

Answer 2

Given,

Distance covered by a person=90km

Time taken=2hours 30mins

To Find,

Velocity of a person.

Solution,

We have to calculate velocity by using distance and time taken.

So, formula for velocity= distance/time

                                  V   = 90km/2.5hr

                                        =36km/hr.

According to question we have to convert it into m/s

So 1km/hr=5/18m/s

   36km/hr=10m/s

Hence, its velocity is 10m/s.
