I have to do this assignment for Algebra 2 but I'm stuck. -_-

1.Discuss with another student, parent/guardian, or a friend a common activity the two of
you share.
2.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.

3.The rational equation based upon the scenario above would be 1/2 + 1
