In basketball, hang time is the time that both of your feet are off the ground during a jump. the equation for hang time is t=2(2h/32)^1/2, where t is the time in seconds, and h is the height of the jump, in feet.

player 1 had a hang time of 0.9 s. player 2 had a hang time of 0.8 s. to the nearest inch, how much higher did player 1 jump than player 2?
.
is it 8? because i solved the problem and player 1s jump height minus player 2 is 0.68 feet which is 8.16 inches?
