At the park, Naomi saw people riding 7 regular bikes and 11 children's bikes. Regular bikes have 2 wheels and kid's bikes have 4 wheels. How many wheels did Naomi see at the park?
Thoughts? Step-by-step reasoning:
For the regular bikes, there are 7 x 2 = 14 wheels. For the children's bikes, there are 11 x 4 = 44 wheels. Altogether, Naomi saw 14 + 44 = 58 wheels.
Thus, the answer is 58.
