help!

OpenStudy (anonymous):

Discuss with another student, parent/guardian, or a friend a common activity the two of you share that can be completed faster by working together. Running miles or swimming laps cannot be done faster by working together. Painting a room, building a sandcastle, or aphabetizing your files can be done faster with someone helping. Write a word problem describing the time it takes to complete this activity individually and together. For example, if John takes 2 hours to mow his lawn and it takes his sister, Maria, 4 hours to mow the same lawn, how long would it take John and Maria to mow the lawn together? Write a rational equation based upon the word problem you created.

Why not ask a parent, it says discuss with a parent/guardian.

The Johnson's are moving to another house. It's takes dad 5 hours to pack all the boxes and it takes 3 hours for mum to pack them. If mom and dad work together, how many hours will it take them to pack all the boxes?

OpenStudy (anonymous):

OpenStudy (primeralph):

I was not asking a question. The stuff I typed is the answer to the problem.

OpenStudy (primeralph):

And it's actually not 8.
