Solve the following automotive-services problems based on the examples shown previously. Choose the correct answer. 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.
Drive-shaft speed = 650 r.p.m.

Answer: 1950 r.p.m.

Step-by-step explanation:

Given: In  first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft.

If Drive-shaft speed d= 650 r.p.m.

Then, the engine speed (e) is given by :-

[tex]e=3d[/tex]

If Drive-shaft speed d= 650 r.p.m. , the the engine speed will be:-

[tex]e=3\times650=1950\ r.p.m.[/tex]

Hence, in first gear Engine speed =1950 r.p.m.
