Question

A car travels at a speed of 20km/hr for hr. & at 60km/hr for next 2hrs .What is the average speed of the car.

Answer 1

Answer:

40km/hr

Explanation:

a car is travelling certain distance in certain time as

for 2 hr with 20 km/hr = 2 × 20 = 40 kms will be covered

for another 2 hrs 60 km/hr =  2 × 60 = 120 kms will be covered

total distance covered = 40kms + 120kms = 160kms

total time taken is = 2hrs + 2hrs = 4hrs

average speed = ( total distance ) / ( total time ) = 160/4 = 40km/hr

average speed of the car is 40km/hr
