Working alone it takes jull 8.4 hours to pick forty bushels of apples. Maria can pick the same amount in 15 hours. If the worked together how long would it take them

5.39 hours

Step-by-step explanation:

For Jill:

Number of hours used = 8.4 hours

Number of bushels of apples picked = 40

Number of bushels of apples picked per hour will be: = 40/8.4 = 4.7619

For Maria:

Number of hours used = 15 hours

Number of bushels of apples picked = 40

Number of bushels of apples picked per hour will be: = 40/15 = 2.6667

We then add the number of bushels of apples picked per hour for both of them together. This will be:

= 4.7619 + 2.6667

= 7.4286

If they worked together, the hours they'll take to pick 40 bushel of apples will be:

= 40/7.4286

= 5.39 hours

answer: 5100 just subtract
