Answer 1

To find the rate at which Sam walked, we can use the formula \( r = \frac{d}{t} \), where:

• \( d \) is the distance (4 kilometers),
• \( t \) is the time (50 minutes).

Using the formula, we can calculate the rate:

\[ r = \frac{d}{t} = \frac{4 \text{ kilometers}}{50 \text{ minutes}} = 0.08 \text{ kilometers per minute} \]

Therefore, the correct response is:

0.08 kilometers per minute.
