Question

Isaac and Juanita are collecting apple to make an apple pie. Isaac picks up 3 apples every minute and Juanita picks up 5 apples every two minutes. If they need 40 apples for a pie, about how long will it take both of them to collect enough apples?

Answer 1

about 7 minutes (7.27 minutes to be exact)

Explanation:

Since they are working as a team, we can combine the two rates to see how many apples they collect together per minute. Isaac collects 3 p/min while Juanita collects 2.5 p/min equaling 5.5 apples p/min. 40 apples divided by 5.5 equals 7.27 minutes.

Hope that helped!!

Answer 2

It will take them roughly 7.27 mintues

Explanation:

To find this, model the amount of apples that can collect a minute using m as the minutes.

Isaac = 3m

Juanita = 5m/2

Now we can add them together and solve for when they will have 40 apples.

3m + 5m/2 = 40

5.5m = 40

m = 7.27
