Circular gears p and q start rotating at the same time at constant speeds. gear p makes 10 revolutions per minute and gear q makes 40 revolutions per minute. how many seconds after the gears start rotating will gear q have made exactly 6 more revolutions than gear p ?
a. 6
b. 8
c. 10
d. 12
e. 15

12 minutes

Option D

Step-by-step explanation:

Given that circuar gears P and Q start rotating at the same time at constant speeds.

Gear P makes 10 revolutions per minute and Gear Q makes 40 revolutions per minute.

Both gears start at the same time.

No of rotations per minute are 10 and 40

Difference is 30 in one minute

For 6 difference we must have exactly 1/5 minutes

which equals 12 seconds.

In 1/5 minutes or 12 seconds  gear P would have completed 2 revolutions while Gear Q would have completed 8 revolutions thus making difference as 6.
