In first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft. In second gear, the engine does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft. Finally, in third, or high gear, the engine runs at the same speed as the drive shaft.
Suppose an engine is running 2,000 r.p.m. in second gear. How fast is the drive shaft running?
Drive shaft rotation = r.p.m.

Solve the following automotive-services problem.
In first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft. In second gear, the engine does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft. Finally, in third, or high gear, the engine runs at the same speed as the drive shaft.
Engine speed = 2,575 r.p.m.
Transmission in second gear
Drive-shaft speed (to nearest r.p.m.) = r.p.m.
