Solution
Verified by Toppr

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=totaldistancetravelledtotaltimetaken
Vaverage=x+xxv1+xv2=2xx20+x30=24 km h1
