6:5 to 24:20
thats because 6 to 24 is 4 times so you do 5 times 4 and get 20.
The function is symmetric in the line that goes trough the top. The top is on t=2.5 seconds. If you want to know on which time the height is equal to 15 feet, you draw a line on that height in the graph and see where it crosses. That is at t=1.25 and t=3.75
