ratio
18 miles on the bicycle, 60 miles on the motorboat.
The index of refraction.
It is the average speed.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
the faster the speed of the bicycle,the brighter the lamp
No, bicycle gears do not change the direction of motion. They adjust the ratio of pedal rotation to rear wheel rotation, allowing the rider to maintain an optimal cadence and control the speed and effort required while riding.
The speed ratio of turbines refers to the ratio of the rotational speed of the turbine rotor to the rotational speed of the turbine shaft. This ratio is important for defining the mechanical performance and efficiency of the turbine.
Braking reduces speed.
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.
The average velocity of a bicycle going at a constant speed in a constant direction is equal to the speed of the bicycle. It is a vector quantity that indicates the displacement covered by the bicycle in a given time period, taking into account both the distance and the direction.
If there is no friction, the bicycle's speed will remain constant due to inertia. Once set in motion, it will continue at the same speed unless acted upon by an external force.
ratio
The top speed for a bicycle depends on the rider (strength, stamina, coordination, muscle speed), the gearing of the bicycle, and the terrain it is being ridden over. The current record speed is 268.831 km/h - which was set on a specially designed bicycle ridden behind a dragster (to eliminate most of the air drag) on October 3, 1995 on the Bonneville Salt Flats in Utah, USA.

When he's gaining speed
The invention of the multi-speed bicycle increased the usefulness of the vehicle. It made it easier to pedal up hills giving it much more range.
