To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions
4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions
Answer:
f=16/7.3x
Step-by-step explanation:
Lets solve for f:
f(7.3)=16
Step 1:Divide both sides by 7.3x
7.3f/7.3x=16/17.3x
f=16/7.3x
