Question

You paint 1/2

wall in 1/4

hour. At that rate, how long will it take you to paint one wall?

Answer 1

If you can paint \( \frac{1}{2} \) of a wall in \( \frac{1}{4} \) hour, you can find out how long it will take you to paint one wall by first determining how long it takes to paint a whole wall.

Since \( \frac{1}{2} \) of a wall takes \( \frac{1}{4} \) hour, painting a whole wall will take twice that time:

\[
\text{Time to paint 1 wall} = 2 \times \frac{1}{4} \text{ hour} = \frac{2}{4} \text{ hour} = \frac{1}{2} \text{ hour}
\]

So, it will take you \( \frac{1}{2} \) hour to paint one wall. In minutes, this is \( 30 \) minutes.
