Question

1. a wave travels $\frac{1}{3}$ mile in $\frac{1}{20}$ hour. at this rate, how far will the wave travel in 1 hour? (example 2)

Explanation:

Step1: Identify the rate - formula

Rate = Distance / Time. We want to find the distance in 1 hour. Let the distance be $d$. The given rate is $\frac{\frac{1}{3}}{\frac{1}{20}}$.

Step2: Calculate the rate

Using the rule for dividing by a fraction ($\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}$), we have $\frac{\frac{1}{3}}{\frac{1}{20}}=\frac{1}{3}\times20=\frac{20}{3}$ miles per hour.

Answer:

$\frac{20}{3}$ miles
