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 = 3,500 r. p.m.
transmission in first gear

drive-shaft speed (to nearest r. p.m.) =.

a.1,167b.2,188c.5,600d.10,500

Given:

They want to know drive shaft speed when transmission is in 1st gear. It is given in the problem that in first gear,

engine speed = 3 times as drive shaft

Let's solve this by putting 3500 in engine speed. We have,

3500 = 3 * drive shaft speed

drive shaft speed = . Rounding to nearest number is 1167 (rpm). Answer choice A is the right one.

ANSWER: A

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer

hope i
