Answer 1

Ivan can paint 25 square feet every half hour. In 3 hours, there are 6 half-hour intervals (since 3 hours × 2 half-hours per hour = 6 half-hours).

To find out how many square feet he can paint in 3 hours, we can multiply the number of half-hour intervals by the amount he can paint in each interval:

\( 6 \text{ half-hours} \times 25 \text{ square feet per half-hour} = 150 \text{ square feet} \).

So, Ivan can paint **150 square feet** in 3 hours.
