A train travels 40 km/hr for 0.2 hr, 50km/hr for next 0.2hr and 60km/hr for next 0.4 hr.calculate the average speed of train.
My Solution:-1st hr. distance=40 multiplied by 0.2=8km
2nd hr.= 50 multiplied by 0.2=10km
3rd hr. =60 multiplied by 0.4=24 km
Average speed=10+24+8 divided by 0.8=52.5 km
IS IT RIGHT
