Question

abdul, while driving to school, computes the average speed for his trip to be 20 km/h. on his return along the same route, there is less traffic and the average speed is 30 km/h. what is the average speed and average velocity for abdul's trip?

Answer 1

Hence class (30,20)
Average speed = (Upper limit + Lower limit)÷2
= (30 + 20) ÷ 2
= 50÷2
= 25
$hence \: average \: speed \: is \: 25km \: per \: hr$
