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
Answer:
14
Step-by-step explanation:
a = 3
b = 4
Answer:
Yes
Step-by-step explanation:
All of those are correct because the most is at three and three is in the center. 4 and 5 have a gap from 4 to 1 miles. and most of the miles is on the left.

Explanation:
Theorems about triangles identify relationships that can be used to formulate equations that can be used in the problem-solving process.
The idea with problem solving is to start with what you know, and make use of the relationships between that and what you don't know in order to find a solution.
