Answer:
B
Step-by-step explanation:
First, you much find out how many houses are deliverd in 1 hour.
130/2.5=52
So 52 houses are delivered in 1 hour. Now, divide that by 312.
312/52=6
It would take 6 hours to deliver 312 houses.
The second in the top row is this:
42.4-1.5(TIMES)3.1
42.4-46.5
-4.1
What does it say 3.5 or 3.50
