Question

This morning, Sam walked 4 kilometers in 50 minutes. At what rate did Sam walk?

Use the formula r = StartFraction d Over t EndFraction, where r is the rate, d is the distance, and t is the time,
0.08 kilometers per minute
12.5 kilometers per minute
46 kilometers per minute
200 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 (4 kilometers),
- \( t \) is the time (50 minutes).

Now, let's calculate:

\[
r = \frac{4 \text{ km}}{50 \text{ min}} = 0.08 \text{ km/min}
\]

So, the rate at which Sam walked is **0.08 kilometers per minute**.
