Answer 1

Answer:

hello dear

Explanation:

Let the length of the line segment AB be x m

The time taken is given as t=distance covered/speed

Total time =   t₁+t₂   =  x/30+  x/20=  5x/60h

Average speed = Total distance/Total time =   2 x

​                                                                      5x/60

=24 km/h

hope this helps u
