Answer:
79.3
Step-by-step explanation:
2,037,634= 100 percent
1,614,840=x
x=1,614,840×100÷2,037,634
x=79.25
The speed is the ratio between the distance and the time:

Data:
d=6343miles
t=9h

Then, the plane traveled at a speed of 704.77 miles per hour.
4(-5y) + 2y = 180
-20y + 2y = 180
-18y = 180
y = -10
x = 50
