Answer:
7.27 min
Step-by-step explanation:
Given: Isaiah pick 3 apple in one minute.
Juanita pick 5 apple in two minutes.
They need to pick 40 apples.
Now, finding number of apple picked by Juanita in one minutes.
As given, Juanita pick 5 apple in two minutes.
⇒ Number of apple picked by Juanita in one minutes= [tex]\frac{5}{2} = 2.5 \ apples[/tex]
∴ Total number of apples picked by Isaiah and Juanita in one minute= [tex]3+2.5[/tex]
Hence, Total 5.5 apples picked by Isaiah and Juanita in one minute.
Next finding time taken to pick total 40 apples for a pie.
⇒ Time to pick 40 apples= [tex]\frac{40}{5.5} = 7.27 \min[/tex]
Hence, 7.27 minutes taken to pick 40 apples.
