5km/h

average speed = 4km/h + 6km/h

___________

2

=5km/h

Answer 2

Answer:

S=vt

Distance = velocity x time

Explanation:

He travelled 6 km in total

Let's know how to calculate avg speed

Average speed = Total distance/total time

In this formula, you can see time as well but is not given in the question, right.

So we will find the time the man took for going to market and coming back home.

Now, time taken for going to market=

Distance/velocity=3/4hr

And time taken for coming back home=3/6=1/2hr

Total time=3/4+1/2=5/4

Yay! We got the time, now put these values in the above formula, that is

Average speed = Total distance/total time

Avg speed=6/(5/4) = (6 x 4)/5 =4.8km/h

Congrats!
