speed

1. choose the best answer.

willow runs down a sidewalk that is 128 m long in 32 s.
what is her speed?

3.5 m/s
4 m/s
4.7 m/s
5.2 m/s

Explanation:

Step1: Recall the formula for speed

The formula for speed \(v\) is \(v=\frac{d}{t}\), where \(d\) is distance and \(t\) is time.

Step2: Substitute the given values

Given \(d = 128\space m\) and \(t=32\space s\). Then \(v=\frac{128}{32}\).

Step3: Calculate the value

\(\frac{128}{32}=4\).

Answer:

1. speed
2. \(4\space m/s\)
