A car has to cover a distance of 600 km.
Suddenly it got a break down so that the speed of the car has been reduced to 200
km/hr and the time also increased by 30 min.
what is the time taken to cover the distance ??
:
From the answers given, the only one that is possible is (d) 3 hrs (600/200 = 3)
then to find the normal speed (s), the time would be a half hr less or 2.5 hrs
= 2.5
s = 600/2.5
s = 240 km/hr is the normal speed
