    its height is just 2 feet, whereas the actual ramp was 12feet.

    now this is the key :- since the model is 6 times smaller than actual ramp, PR will also be 6 times smaller than JL

    Since QP(2feet) in model is smaller than JK(12feet) in actual ramp by 12 times, all dimensions in model have to be smaller than actual ramp by 6 times. From the grid, length of JL = 24. JL is represented in model as PR. Since PR has to be 6 times smaller than JL. so PR = 24/6 = 4 feet. Since P is fixed in grid at (30, 20), R point which is 4feet from P can be at (30+4, 20) = (34, 20).
