Based on the areas of the pistons and the length to be lifted, you should push down piston 1 by 15 ft.
How much should Piston 1 be pushed down by?
Area of piston 1 x Length to push piston 1 by = Area of piston 2 x Length to be lifted by
A1 x L1 = A2 x L2
L1 = A2 / A1 x L2
Note that A2/A1 is 15 because A1 is 15 times smaller than A2
Solving gives:
L1 = 15 X 1
= 15 feet
