Question

question 1 - 6
motion of a beetle
display top - to - bottom
according to the graph and the formula above, what is the average speed of the beetle from 0 - 20 seconds?
average speed = total distance / time
0.0 cm/s
0.3 cm/s
0.6 cm/s
3.3 cm/s

Explanation:

Step1: Determine total distance

From the graph, at \(t = 0\) seconds, \(d=0\) cm and at \(t = 20\) seconds, \(d = 12\) cm. So total distance \(d=12\) cm.

Step2: Determine total time

The time interval is from \(t = 0\) to \(t = 20\) seconds. So total time \(t = 20\) seconds.

Step3: Calculate average speed

Using the formula \(v=\frac{d}{t}\), substitute \(d = 12\) cm and \(t = 20\) s. Then \(v=\frac{12}{20}=0.6\) cm/s.

Answer:

\(0.6\) cm/s
