Answer:
24 km/hr.
Explanation:
Let the equal distance covered by the boy be d.
Speeds given - 20 km/hr and 30 km/hr
Time in 1st case = distance /speed = d/20
Time in 2nd case = d/30
☆ Total time = d/20 + d/30
= 5d/60
☆ Total distance = d + d
= 2d
Average speed = total distance/ total time
= 2d / 5d / 60
= 2d × 60 /5d
= 12 × 2
= 24 km/hr
hope it will help you
