Question

The world record for the most number of speed skips in 60 seconds is 332 skips. If the record holder skipped at a constant ratio of seconds to skips, how many skips did she make in 15 seconds?

Answer 1

332/60 is 5.53, then multiply that by 15 and your answer is 83

Explanation:

Answer 2

83

Explanation:

If that number of skips is represented by s, we can write the proportion ...

skips/seconds = s/15 = 332/60

s = 332(15/60) = 332/4 = 83

She skipped at the rate of 83 skips in 15 seconds.

Additional comment

If the ratio seconds : skips is constant, then so will be the ratio skips : seconds.
