Question

# A car moves for half of its time at $$80$$ km/h and for rest half of time at $$40$$ km/h total distance covered is $$60$$ km what is the average speed of the car?

Solution

## Let the time taken be 't' hours. average speed= total distance covered/total time taken distance covered with 80km/h speed. 80*t/2=d1 40t=d1 distance covered with 40 km/h speed 40* t /2=D2 20t=D2 average speed of car= (40t+ 20t)/t 60km/h is the average speedPhysics
