To calculate the gear ratio on a bicycle, divide the number of teeth on the front chainring by the number of teeth on the rear cog. This will give you the gear ratio, which represents how many times the rear wheel turns for each rotation of the pedals.
Each stop for gas you take turns paying then you add up each amount you payed and one of you pays the difference.
If the bicycle travels 4 miles for the car's 30 miles, then if you divide both numbers by 3 you'll see that the bicycle travels 1 and 1/3rd miles for each 10 miles that the car travels. So, if the car travels a further 10 miles (and has now gone 40 miles) the bicycle will travel a further 1 and 1/3rd miles and its total travelled would be 5 and 1/3rd miles.
A standard adult bicycle typically has 32 or 36 spokes on each wheel.
Each of them does.

A dicycle is a vehicle with two wheels parallel to each other, while a bicycle has a wheel followed by another.
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
You know that each 'wrap' or turn of wire in the coil has to go all the way around the coil-form, and you know how to calculate the distance around a circle. So all you have to do is count the number of times the wire goes around the coil, measure the coil's diameter, calculate its circumference, and multiply that by the number of turns in the coil.
Diameter = 88.84 inches
