Answer:
1 - 3.54 hours / total flight time - 4.54
2 - 15/22
Step-by-step explanation:
First, you need to find the speed of the plane for the rest of the flight.
In the last 2 hours, it flies 830 miles.
In the last 1/2 hour, it flies at 160 mph so it travels 80 miles.
So in the middle of the flight, it travels (830 - 80) = 750 miles in 1 1/2 hours
Speed = 500 mph
Now think about the whole flight. There is 1 hour at 160 mph plus x hours at 500 mph.
Distance = 160 + 500x = 1930
500x = 1770
x = 3.54 hours
Total flight time = x + 1 = 4.54 hours
