Answer:

  6 h

Step-by-step explanation:

The bottom number in the table is half the top number. The missing value is 6 (hours).

__

I like to put the variable in the numerator of a proportion. Here, we can write it as ...

  t/12 = 45/90

Multiplying by 12 gives ...

  t = 12(45/90) = 12(1/2) = 6

It will take Darin 6 hours to mow 12 lawns.
