Question

Abdul, while driving to school, computes the average speed for his trip to be 20 km h-1. On his return trip along the same route, there is less traffic and the average speed is 30 km h-! What is the average speed for Abdul's trip?​

Answer 1

Answer:

average speed = spped 1 + speed 2 /2

Explanation:

speed 1 = 20 km/h

speed 2 = 30 km/h

so avg. speed = 20+30/2

= 25 km/h
