Answer 2

Answer:

ANSWER

Let us assume that Abdul is travelling x kilometer distance while going to school.

Distance = Speed x Time

1)When it's average speed is 20 km/hr

x=v1×t1=20×t1

2)When it's average speed is 30 km/hr

x=v2×t2=30×t2

Vaverage=totaltimetakentotaldistancetravelled

Vaverage=v1x+v2xx+x=20x+30x2x=24 km h−1
