- Please help!! Math -
**MathMate**, Sunday, February 19, 2012 at 9:52amThis is probably an exercise on system of equations. However, this can be solved mentally.

40 pedals => 20 pedaling vehicles.

If all bicycles, there are 40 wheels, so we are 10 wheels short. Change 10 bicycles for 10 tricycles will solve that.

So there are 10 bicycles and 10 tricycles.

Check: 20 wheels for 10 bicyles and 30 wheels for 10 tricycles make 50 wheels.
