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? (example 2)

Explanation:

Step1: Find the skip - rate per second

Since in 60 seconds there are 332 skips, the number of skips per second is $\frac{332}{60}=\frac{83}{15}$ skips per second.

Step2: Calculate skips in 15 seconds

Multiply the skip - rate per second by 15 seconds. The number of skips in 15 seconds is $\frac{83}{15}\times15 = 83$ skips.

Answer:

83
