Question

what is the average speed of a toy car that travels 100 centimeters in 20 seconds? a. 5 cm/s b. 100 cm/s c. 20 cm/s

Explanation:

Step1: Recall the formula for average speed

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

Step2: Substitute the given values

Given \(d = 100\) cm and \(t=20\) s. Then \(v=\frac{100}{20}\) cm/s.

Step3: Calculate the value

\(\frac{100}{20}=5\) cm/s.

Answer:

A. \(5\) cm/s
