513 * 40 + 513 * 6= 2052 + 3078 = 5130
Answer:
36 minutes
Step-by-step explanation:
The key is to get the same amount of time for each.
9 * 12 = 108
At 12 minutes per job,
in 108 minutes Alyssa could do
108/12 = 9 jobs
At 9 minutes per job,
Together in 108 minutes they could do
108/9 = 12 jobs
--------------------------
In 108 minutes Mirada does
12 - 9 = 3 jobs
108/3 = 36 minutes per job
The answer to this is 756 hours. Because first you must multiply the number of miles each flight is x the miles per minute. Next you multiply that answer by the number of trips. The answer would be how many minutes, but the question asks "how many hours", and there's 60 minutes in an hour so divide that answer by 60 and that will equal 756 hours.
