Question

Rahul covers a distance of 165 km in 5 and a half hours. Assuming the speed of the car to be constant, how much time will he take to cover a distance of 225 km?

Answer 1

convert 165km to meter
i.e. 165000m
and 5:30hrs to min
i.e. 450min
s=d/t
s=165000/450
=366.6 m/min (approx)
now convert 225 km to m
i.e. 225000m
from s=d/t we have
t=d/s
t=225000/366.6
=613.8 min
i.e. t=10hrs 23min...
therefore Rahul will take 10hrs 23 min to cover a distance of 225km
