1 answer:
Answer:
32 revolutions per minute(rpm)
Step-by-step explanation:
v inversely proportional to t
so if v increases t will decrease and vice versa
inverse equation is xy=k
xy=k
48×20= 960 (revolutions)
then you'll take k(960) and divide it by number of teeth
so..
960/30 = 32 revolutions per minute
