Question

Dan loves to compete in triathlons. At a race a few months ago, he finished in 300 minutes. Yesterday, he completed another triathlon and finished in 306 minutes. What was the percent of increase in Dan's finishing time?

Answer 1

2%

Explanation:

If 300 minutes is 100%, how much percent is 306 minutes?

we need to use the rule of three

306 minutes x 100% / 300 minutes = 102%

Therefore the percent of the increase is 102%-100%= 2%
