To find Mikayla's speed, we can use the formula for speed, which is distance divided by time.
-
Convert the time from minutes to hours since speed is usually measured in miles per hour (mph). \[ 18 \text{ minutes} = \frac{18}{60} \text{ hours} = 0.3 \text{ hours} \]
-
Calculate the speed: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{19 \text{ miles}}{0.3 \text{ hours}} \approx 63.33 \text{ mph} \]
So, Mikayla's speed was approximately 63.33 miles per hour.
