A parachutist jumps from an airplane and immediately opens her parachute.
Her altitude, h, in metres after t seconds is modelled by the equation
h(t) =- 41+ 300. A second parachutist jumps 5 seconds after the first
parachutist jumps. Her altitude, in metres, during this time is modelled by the
equation h(t) =- 4.9(1 - 5)2 + 300. When are the both parachutists at the same
height when falling?
