Answer:

Yes any number can be substituted for h

Step-by-step explanation:

We add all these mixed numbers together:

1 1/2 + 2 3/4 + 2 1/3

It will be easier to convert the mixed numbers into improper fractions:

3/2 + 11/4 + 7/3

Now we have to find the common denominator which is 12:

18/12 + 33/12 + 28/12 = 79/12 = 6 7/12

The answer is 6 7/12 hours.
