Answer 1

Answer:

20Km/h

step-by-step explanation:

Carefully observe the question, we have to find out average speed and speed is given so first add all speed given in the question to find out total speed ok so let's start...!!

10+20+30 so we get 60 don't forget to give units 60km/h ok

Now, we all know the formula of finding average

Average = 60

--------

3

we added already all speed so we put it directly and why we take 3, because how many elements are there...? 3 so we put 3

And our ans is ready...!!

That is....just divide➗ 60÷ 3 = 20 km/h

Simple this is your ans...☺☺
