Question

Thomas swam 7 laps in two and one-half minutes. At this rate, how many laps would he swim in 20 minutes?

14 laps
20 laps
45 laps
56 laps

Answer 1

Answer: 56* 8 / 8 = 56

Explanation:

Answer 2

Answer: 56 laps (choice D)

Work Shown:

(7 laps)/(2.5 minutes) = (x laps)/(20 minutes)

7/(2.5) = x/20

7*20 = 2.5x

140 = 2.5x

2.5x = 140

x = 140/(2.5)

x = 56
