Question

this question has two parts. first, answer part a. then, answer part b. part a distance - time graph what was swimmer cs average speed? 4.8 km/h 2.4 km/h 2400 km/h 4800 km/h

Explanation:

Step1: Identify distance and time

From the graph, Swimmer C travels a distance of 2400 m in 30 min.

Step2: Convert units

Convert distance to km: 2400 m = 2.4 km. Convert time to hours: 30 min = 0.5 h.

Step3: Calculate average - speed

Use the formula $v=\frac{d}{t}$, where $v$ is average speed, $d$ is distance, and $t$ is time. So $v=\frac{2.4}{0.5}=4.8$ km/h.

Answer:

4.8 km/h
