Question

a car travelled at 60 km/h for 5/2 hours .During the next 2hours it travelled at56km/h for the last 3/2hours it travelled at 50km/hours calculate average speed

Answer 1

I think that there is some problem in the question.. because avg speed = total distance/ total time taken
but here total distance is not given and in place of that total speed is given
write correct question again...

Answer 2

Distance car covers in 5/2 hours =30*5/2=150km
distance car covers in 2 hours =56*2=112km
Distance car covers in 3/2 hours =50*3/2=75 km
Thus;
Average speed=total distance /total time taken
=337*2/12 km/hr=56.16km/hr
