Answer:
11 rides
Explanation:
First Step - Subtract 6 from 40 because that will not be of use for now.
40-6=34
Next Step - divide 34 by 3 to find the number of rides.
(you will end up with a decimal so I rounded it up to a whole number.)
34/3=11 (rounded)
The final answer is 11 rides.
Hope this helped :)
