The mechanical advantage (MA) of a lever can be calculated using the formula:

\[ MA = \frac{\text{Effort arm}}{\text{Load arm}} \]

In this case:

  • Effort arm = 15 meters
  • Load arm = 5 meters

Substituting the values into the formula:

\[ MA = \frac{15 , \text{m}}{5 , \text{m}} = 3 \]

Therefore, the mechanical advantage is \(3\).

The correct response is: 3.
