Question

Acar travelled 81 km . 1/3rd of the first part the car travel with velocity 9km/hr and 1/3rd part moves with 18km/hr and remaining 1/3rd moves with velocity 21km/hr.calculate the average velicity throughout the distance​

Answer 1

Answer:

time taken = 20/40 = 1/2 hrs 2nd time average distance = 20 km speed = 60 km/h time taken by the car is = 20/60 = 1/3 ...

average speed of first distance = 20 km speed = 40 km/h time taken = 20/40 = 1/2 hrs ... More

Distance = 20 km Speed = 40 km/hrTime, t1 = 20/40 = 1/2 hrs Speed = 60 km/h Time, t2 = 20/60 ... More
