20 pts. for who ever can answer this ! 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. a. 4120 b. 7725 c. 1609
