Answer:
- 76.7 million
- 89.1 million
- 75 million
Step-by-step explanation:
Let x represent the arrivals and departures at the third airport. Then the number at the first airport is x+1.7, and the number at the second airport is x+14.1. The total is ...
(x+1.7) + (x+14.1) + (x) = 240.8
3x +15.8 = 240.8
3x = 225
x = 75
x+1.7 = 76.7
x+14.1 = 89.1
The first airport has 76.7 million arrivals.
The second airport has 89.1 million arrivals.
The third airport has 75 million arrivals.
So the way to answer this question is to convert minute to seconds
We know that a minute has 60 seconds
The problem states that the hummingbird flaps its wings 80 times per second
So 80 times per second x 60 seconds = 4800 times would be the final answer.
