Answer: 187.7 mph
Step-by-step explanation:
v = 125 mph
t = 1.2 min
v2 = ?
t2 = 0.8 min
We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.
![\frac{125mph}{x} =\frac{1.2min}{0.8min}](https://tex.z-dn.net/?f=%5Cfrac%7B125mph%7D%7Bx%7D%20%3D%5Cfrac%7B1.2min%7D%7B0.8min%7D)
![x = \frac{(125)(1.2)}{0.8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B%28125%29%281.2%29%7D%7B0.8%7D)
![x=187.5mph](https://tex.z-dn.net/?f=x%3D187.5mph)
Answer:
180 CDs
Step-by-step explanation:
So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
Answer:
D
