1) A factory produces 12 cars in 20 days how many days will it take to make 21 cars at this rate?

1 answer:

5 0

1) The factory will produce 3/5th or 0.6 of a car per day (12 cars / 20 days = 0.6 car per day). The equation for the answer is: 21 / 0.6 = X. The answer is 35 Days.

2) You divide 45 by 3. You do this by multiplying 45 by 1/3, which is 15. You add 15 to 45, and you get a speed of 60 MPH.
