To find the distance Barry rode on his scooter, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
In this case, Barry's speed is 0.5 miles per minute, and he rode for 24 minutes. Plugging in the values:
\[ \text{Distance} = 0.5 , \text{miles/minute} \times 24 , \text{minutes} = 12 , \text{miles} \]
So, the distance Barry rode is 12 miles.
