Question

Pierre is rowing his kayak on a lake. He moves miles in 18 minutes. At this rate, how far would he move in 30 minutes?

Answer 1

To calculate how far Pierre can move in 30 minutes, we first need to determine his speed in miles per minute.

1. **Calculate speed**:
- Pierre moves \( x \) miles in 18 minutes. Therefore, his speed in miles per minute is:
\[
\text{Speed} = \frac{x \text{ miles}}{18 \text{ minutes}}
\]

2. **Calculate distance in 30 minutes**:
- To find out how far he can go in 30 minutes, we multiply his speed by 30 minutes:
\[
\text{Distance in 30 minutes} = \text{Speed} \times 30 = \left(\frac{x}{18}\right) \times 30
\]

Simplifying this:
\[
\text{Distance in 30 minutes} = \frac{30x}{18} = \frac{5x}{3}
\]

So, if Pierre moves \( x \) miles in 18 minutes, he would move \( \frac{5x}{3} \) miles in 30 minutes.

To obtain a numerical distance, you would need the value of \( x \), which is the distance he traveled in the 18 minutes.
