Answer:
The diameter is 47
Step-by-step explanation:
Given
--- Circumference
![\pi = 3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D%203.14)
Required
Determine the diameter (d)
The circumference of a circle is:
![C = \pi d](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20d)
Make d the subject
![d = \frac{C}{\pi}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7BC%7D%7B%5Cpi%7D)
![d = \frac{147.58}{3.14}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B147.58%7D%7B3.14%7D)
![d = 47](https://tex.z-dn.net/?f=d%20%3D%2047)
I think Jordan would be 16 and Kevin would be 8. Sorry if this is wrong...
The average speed of Martha and Sarah is 32 km/h.
We need to know about the speed to solve this problem. Speed can be determined as the distance traveled divided by time. It can be written as
v = s / t
where v is speed, s is distance and t is time.
From the question above, we know that:
t sarah = 3 hours
t martha = 5 hours
v sarah = 40 km/h
By using the speed equation, we get the distance
vsarah = s / tsarah
40 = s/3
s = 120 km
Find Martha's speed
vmartha = s / tmartha
vmartha = 120 / 5
vmartha = 24 km/h
Find average speed
v = (vsarah + vmartha)/2
v = (40 + 24) / 2
v = 32 km/h
Hence, the average speed of Martha and Sarah is 32 km/h.
