Answer 1

To find the rate at which Sam walked, we can use the formula:

\[ r = \frac{d}{t} \]

Where:

• \( d \) is the distance (6 kilometers),
• \( t \) is the time (50 minutes).

First, we convert the time from minutes to hours for better understanding, but it can also stay in minutes for our calculation. However, since we are calculating in kilometers per minute:

1. Calculate the rate:

\[ r = \frac{6 \text{ kilometers}}{50 \text{ minutes}} \]

2. Now calculate that:

\[ r = 0.12 \text{ kilometers per minute} \]

Thus, the correct answer is:

0.12 kilometers per minute.
