S.I. unit of speed is m/s

So we need to convert all the values to S.I. unit

Distance =2.5 km=2.5×1000=2500.0 meters

Time=5 minutes= 5×60=300 meters

We know that ,

Speed= $\dfrac{Distance}{Time}$

= $\dfrac{2500}{300}$

= $8.33\:m/s$

Hence speed =8.33m/s

A man covers 2.5km in 5 minutes. what will be the speed in km/ hr?

Speed = Distance / Time

Distance = 2.5 km

Time = 5 mins or 5/60 hour ( we have to convert the time to hours as the required answer is in km/hr)

Thus,

Speed = 2.5* (60/5)

= 30 km/hr
