Answer:

6 weeks

Step-by-step explanation:

It is simple logic, you can only create what you have, so in what Ben can make in 6 weeks is 9 apps and john creates 3 apples in 6 weeks, so if you do the math, you get 12 apps in 6 weeks all together.

Answer:

5 Weeks


Step-by-step explanation:

Rate of John would be [tex]\frac{3Apps}{6Weeks}=\frac{0.5Apps}{1Week}[/tex]

So John's rate is 0.5 apps per week


Rate of Ben would be [tex]\frac{3Apps}{2Weeks}=\frac{1.5Apps}{1Week}[/tex]

So Ben's rate is 1.5 apps per week.


So, in 1 week, two of them together can create [tex]1.5+0.5=2[/tex] apps

So it would take them [tex]\frac{10}{2}=5[/tex] weeks to make 10 apps, together.
