(40+x)/2=60
40 +x = 120
x = 80
check :
40+80 = 120
120/2 = 60
so his second round needs to be 80 mph
The surface area is 216
The Volume is 216
The diagonal is 10.392
Since X increases by 1,
Divide the 2nd Y value by the first Y value:
4/6 = 2/3
The answer is 2/3
A bit of a shot in the dark, I think it is 1-s^2.
