Problema Solution
Mei can pick forty bushels of apples in six hours. One day her friend Cody helped her and it only took 3.75 hours. Find how long it would take Cody to do it alone.
Answer provided by our tutors
Mei can pick 40 bushels of apples in 6 hours meaning her rate per hour is: 40/6 = 20/3 bushels per hour
Let 'x' represent the time that Cody needs to pick 40 bushels alone thus Cody's rate is: 40/x bushels per hour
The together rate of Mei and Cody is: 40/3.75 bushels per hour
20/3 + 40/x = 40/3.75
