Answer 1

Hi friend,

# 24km/hr

➡Solution :- This question is very simple to answer.

Avg. Speed = Total distance / total time taken

➡Using simple formula :-


➡Avg. Speed = 2xy/x+y

X = 20 and y = 30


➡So, Avg. Speed = 2 × 20×30/50

= 1200/ 50
= 24km/hr

So, Avg. Speed = 24km/hr..i hope it helps you
