Step-by-step explanation:
In the first part, he was travelling with twice the speed, or Vs, for distance
48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part :
48 - d = 2V * 2
⇒d + 4V = 48
Second part:
d = V * 2
⇒d = 2V
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48
s = 8
The speed in the second part is 8 mph.
<u>The speed in the first part is 2s = 2(8) = 16</u>
I hope this helps

Hello,
the length of the circomference is 2*π*radius
=2*π*105=659,7344572538565800771551104887... (m)
An easy way to find it (aka the avarage) is to add the two numbers together and divide the result by 2 so
15+37=52
52/2=26
another way is to subtract 15 from 37 and divide the result by 2, then you add this to the smaller number so
37-15=22
22/2=11
15+11=26
also
37-11=26
