Question

Nick participated in the swimming competition held by the town recreation center. He swam 315 yards in 7 minutes. If he swam at a constant rate, how fast did he swim in yards per minute?

Answer 1

Nick swam `45` yards per minute.

Explanation:

You can use a proportion to solve this:

`(315 " yds")/(7 " min") = (45 " yds")/(1 " min")`

And check your work by multiplying the time by rate of speed:

`7*45=315`
