Okay, here we need to calculate the rate in miles per minute:
[tex]\begin{gathered} 18\frac{miles}{hour}\cdot\frac{1\text{ hour}}{60\text{ minutes}} \\ =\frac{18\text{ miles}}{60\text{ minutes}} \\ =0.3\text{ miles/minutes} \end{gathered}[/tex]
The rate in miles per minute is 0.3 miles/minute.
To know how many miles will the cyclist travel in 20 minutes we are going to multiply the miles per minute by 20 minutes, let's do it:
[tex]\frac{0.3\text{ miles}}{minute}\cdot20\text{ minutes=}6\text{ miles}[/tex]
Finally we obtain:
Rate: 0.3 miles/minute
Distance traveled in 20 minutes: 6 miles
