Answer:
Explanation:
To answer this question is fairly simple:
Firstly, look at the miles traveled per hour in the number sequence. Notice that 1/410 is the starting point, since 2/820 is just multiplying the numerator and the denominator by 2. Basically, the numbers are multiples. Just multiply 410 by the number on top of the other numbers to get the answer.
From there, you know that the number you have to multiply into 410 is gonna be the number of hours the flight was. Divide 4920 by 410, and you get 12. Hope this helps!
