Answer:
10 km/h
Step-by-step explanation:
I'm not really sure about this but no ones answering your question and I wanna help.
So basically to calculate the average speed you need to divide the distance travelled by time taken
But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km
Now that we have the time and distance all we have to do is find the average speed.
Average Speed = distance ÷ time
So 150 ÷ 15 = 10 km/h

Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
A semicircle is given with radius of 3cm .
And we need to find the perimeter of the semicircle . We know the perimeter as ,
Perimeter = πr
Perimeter = 3cm × π
Perimeter = 3π cm .
Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,
Perimeter = 3π + 6 cm
We were supposed to give answers in terms of π .
<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
