Question

the graph shows the distance in meters (m) and the time in minutes (min) for a swimmers workout. swimmer workout distance (m) time (min) text alternative average speed is calculated using the following equation: average speed = total distance/total time what is the swimmers average speed from 15 minutes to 25 minutes? a) 27 meters/minute b) 30 meters/minute c) 40 meters/minute d) 44 meters/minute

Explanation:

Step1: Find the total distance

From the graph, at \(t = 15\) min, \(d_1=800\) m and at \(t = 25\) min, \(d_2 = 1100\) m.
Total distance \(d=d_2 - d_1=1100 - 800=300\) m.

Step2: Find the total time

Total time \(t = 25 - 15=10\) min.

Step3: Calculate average speed

Using the formula \(v=\frac{d}{t}\), substitute \(d = 300\) m and \(t = 10\) min.
\(v=\frac{300}{10}=30\) meters/minute.

Answer:

B. 30 meters/minute
