Question

A person covered a distance of 150 km in 3 hours by a car how much additional time will be required to cover a for the distance of 125 kilometre the same speed

Answer 1

Distance(s)=150km

Time(t)=3 hours

Then, in 1 hour car cover distance=150/3=50km per hour

So, in 5 hour car cover a distance=50*5=250 km
= 250km.

Answer 2

a person covered distance of 150 km in 3 hours therefore
the speed =150÷3=50km/hr
now with same speed it covers the distance 125 kilometre there for the required time is
time=dist./speed
time=125/50=2.5hr
therefore no additional time is required as it covers the distance in 2.5 hour while the distance of 150 km he recover in 3 hours
