Question

A car travels at a speed 40km/hr for 2 hours and then at 60km/hr for 3 hours .What is the average speed of the car during the entire journey?

Answer 1

speed=distance/travel time
distance=2*40+60*3
              =80+180
              =260 km
travel time=2+3=5 hrs
∴ average speed during the whole journey=260/5
                                                                   =52 km/h

Answer 2

Total distance covered is 260 km..
Time is 5 hrs
So average speed will be
$\frac{260}{5} = 52km \: per \: hr$
