In a certain town, the ratio of the number of bicycles to the number of cars is 3:5. If there are a total of 240 vehicles (bicycles and cars) in the town, how many bicycles are there?
Let the number of bicycles be represented by b and the number of cars be c. Based on the ratio, we can express the relationship as:
$$ \f\frac{b}{c} = \f\frac{3}{5} $$
From the total number of vehicles, we also have:
$$ b + c = 240 $$
Using these equations, find the number of bicycles.
