[Free] 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 [tex]$t=2\left(\frac{2 h}{32}\right)^{\frac{1}{2}}$[/tex], where [tex]$t$[/tex] is the time in seconds, and [tex]$h$[/tex] 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? $\square$ in.
