Algebra Math Help

Solve this algebra q?

When a skydiver jumps from an airplane, the time (t) it takes to free fall a given distance can be estimated by the formula t= sqrt(2s/9.8) where t is in seconds and s Is in meters. If Julie jumps from an airplane, how long will it take her to fall 750 meters?

Plug 750 in for s

t=sqrt(2(750)/9.8)
t=sqrt (1500/9.8)
t=sqrt (153.061)
t=12.3699
