Question

This morning, Sam walked 4 kilometers in 50 minutes. At what rate did Sam walk?
Use the formula r = d/t where r, is the rate, d is the distance, and t is the time.
(1 point)
• 12.5 kilometers per minute
• 0.08 kilometers per minute
• 200 kilometers per minute
• 46 kilometers per minute

Answer 1

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

1. **Distance (d)** = 4 kilometers
2. **Time (t)** = 50 minutes

Now, plug in the values into the formula:

\[
r = \frac{4 \text{ kilometers}}{50 \text{ minutes}} = \frac{4}{50}
\]

Calculating that:

\[
r = 0.08 \text{ kilometers per minute}
\]

So, the correct answer is **0.08 kilometers per minute**.
