Question: 1 / 400

If it takes 3 hours to paint a wall, how long will it take to paint 5 walls?

10 hours

12 hours

15 hours

To determine how long it will take to paint 5 walls based on the time it takes to paint one wall, you can apply a simple multiplication method. If it takes 3 hours to paint one wall, then to find the total time to paint 5 walls, you multiply the time taken for one wall by the number of walls.

So, the calculation is as follows:

3 hours per wall × 5 walls = 15 hours total.

This is why the correct answer is 15 hours. It reflects the cumulative time required to complete the task for all five walls, maintaining consistency in the time required for each wall.
