Gear b would rotate: 100 times the number of teeth in gear a divided by the number of teeth in gear b.
60 / 25 = 2.4 RPM (Revolutions per Minute) 2.4 X 10 = 24 RPM
That depends on the relative sizes of the gear shafts used to transmit power from the motor to the wheel. For instance, if they were the same size, and no gears in between, then the wheel would rotate 400 times a minute (RPM), which is 6.66 times a second. But usually gears transmit power in such a way that the wheel rotates slower than the motor (less RPM) but with more power.
No. But if there are two idler gears, one smaller than the other, say a 12 tooth and a 6 tooth. the 12 tooth idler is the idler of the driver gear which has 24 teeth, making the idler gear rotate 2 times for every rotation that the driver gear rotates. Now, if the 12 tooth idler gear is rotating 2 times faster than the driver gear, then the 6 tooth idler gear will rotate 2 times faster than the 12 tooth idler gear. So, the 6 tooth idler gear is rotating 4 times faster than the driver gear. Let's say that the driven gear has 12 teeth. For every rotation of the 6 toothed idler gear, the driven gear rotates halfway.
A pinion gear rotates when it is driven by another gear or motor. As the driving gear turns, its teeth engage with the teeth of the pinion gear, causing it to turn in a specific direction. The rotation of the pinion gear can then transfer motion to another component in a mechanical system, such as a rack or another gear. The speed and torque of the rotation depend on the size and arrangement of the gears involved.
A gear that turns another gear is called a "driving gear." When the driving gear rotates, its teeth engage with the teeth of the adjacent "driven gear," causing it to rotate as well. This interaction allows for the transfer of motion and torque between the two gears, enabling machines and mechanisms to function efficiently. The size and number of teeth on each gear determine the speed and force of the motion transmitted.

Unless a brake is engaged, the wheels on a car in neutral can rotate backwards. If the car is in gear, wheels attached to the power train probably will only rotate backwards if the car is in reverse gear. If it is in forward gear or "park" they should not rotate backwards. Wheels not connected to the power train should be able to rotate either direction.

They use a fixed, gear reduction transmission which reduces the number of rotations of the propeller from the number of rotations of the crankshift. The pilot doesn't do any shifting.
It is the number of rotations of the input shaft to the gearbox as compared to the number of rotations of the output shaft from the gearbox. The ratio will change each time a different gear is selected.
