Question

1. 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?

Explanation:

Step1: Find the rate of skips per second

The record is 332 skips in 60 seconds. So the rate \( r \) (skips per second) is \( r=\frac{332}{60} \).

Step2: Calculate skips in 15 seconds

To find the number of skips in 15 seconds, we multiply the rate by 15. Let \( x \) be the number of skips in 15 seconds. Then \( x = r\times15=\frac{332}{60}\times15 \). Simplify \( \frac{332}{60}\times15=\frac{332\times15}{60}=\frac{332}{4}=83 \) (since \( 60\div15 = 4 \)).

Answer:

83
