Question

This morning, Sam walked 4 kilometers in 50 minutes. At what rate did Sam walk?Use the formula r=dt where r, is the rate, d is the distance, and t is the time.(1 point)Responses0.08 kilometers per minute0.08 kilometers per minute200 kilometers per minute200 kilometers per minute12.5 kilometers per minute12.5 kilometers per minute46 kilometers per minute

Answer 1

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

Given:

• Distance \( d = 4 \) kilometers
• Time \( t = 50 \) minutes

Now, substitute the values into the formula:

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

Therefore, Sam walked at a rate of 0.08 kilometers per minute.
