Homework Help: Math

Posted by bob on Monday, June 17, 2013 at 3:18pm.

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.
