The efficiency of a ramp can be calculated by dividing the work output by the energy input and multiplying by 100.
Efficiency = (work output / energy input) x 100
In this case, the work output is 1,200 joules and the energy input is 2,000 joules.
Efficiency = (1,200 / 2,000) x 100
= 0.6 x 100
= 60
Therefore, the efficiency of the ramp is 60%.
