ANSWER: 184 minutes
EXPLANATION:
1. We first subtract the $3 fee from the total cost (because it doesn't count towards the cost per minute).
[tex]23.24 - 3 = 20.24[/tex]
2. We then divide $20.24 by $0.11 to get the minutes.
[tex]\frac{20.24}{0.11} = 184[/tex]
Therefore, Bob was riding on the scooter for 184 minutes.
