Question

A scale model of a pool from the local park model is 1:25. The depth of the scale pool is 3 cm. How deep is the real pool at the park?

Answer 1

The actual depth of the pool at the park is 75 cm.

Step-by-step explanation:

To find the actual depth of the pool at the park, we can use the scale model and the given depth of the scale model pool. The scale of the model pool is 1:25, which means that every 1 cm on the model represents 25 cm in real life. The depth of the scale pool is 3 cm.

We can set up a proportion to find the actual depth of the pool: 1 cm (model) / 25 cm (real) = 3 cm (model) / x (real). Cross-multiplying gives us 1 * x = 25 * 3, or x = 25 * 3 / 1. So the actual depth of the pool at the park is 75 cm.
