The efficiency of a ramp can be calculated using the formula:

Efficiency = (Useful Energy Output / Total Energy Input) * 100

In this case, the useful energy output is 1,200 joules and the total energy input is 2,000 joules.

Efficiency = (1,200 / 2,000) * 100 = 60%

Therefore, the correct answer is:

60%
