Question 1079535: For a meshed gear of a fixed radius, the number of revelations per minute varies inversely as the number of the gear teeth. If a particular gear had 100 teeth, it would revolve as 10 revolutions per minute(rpm). What rpm would result if the number of teeth were reduced to 25?

For a meshed gear of a fixed radius, the number of revelations per minute varies inversely as the number of the gear teeth. If a particular gear had 100 teeth, it would revolve as 10 revolutions per minute(rpm). What rpm would result if the number of teeth were reduced to 25?
-----
r = k/t
-----
Solve for "k"::
10 = k/100
k = 1000
-----
Equation:
r = 1000/t
Ans: rpm = 1000/25
rpm = 40
