Well subtract 8 from 1000 and then do that five times. so 992,984,976,968, and 960<span />
= 19 this is the answer I'm guessing since 16-12= 4 so 16 is 4 more than 12
So, we know that it takes Sam 1 mph up and 9 mph down and it takes Liam both 2 mph down and up the hill. So if we divide the 2 mph for Liam by 2 miles (the whole length of the hill) we will get 1 or 1 hour. Then we do 1/1 (i don't know how to explain this part of why we do that, sorry) and than we do 1 / 9 and we get 1/9 so we add them and get 1 1/9 so that's Sam's time.
So, Liam took one hour and Sam took 1 and 1/9 hours, in conclusion liam was faster

Answer:
it could be the 5th one !!
Answer:
Step-by-step explanation:
“y varies directly as x”
y = kx
Plug in (4, 1.25) and solve for k:
1.25 = 4k
k = 1.25/4 = 0.3125
The equation becomes
y = 0.3125x
