In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
unicycle relay team:
4 riders
1 rider ===> 1 unicycle
1 unicycle ===> 1 wheel
Step 02:
We must apply the algebraic rules to find the solution.
4 riders * ( 1 unicycle * 1 wheel) = 4 wheels
The answer is:
4 wheels
