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.
The equation of the line is x=2
Answer:
It is 150 percent
Step-by-step explanation:
You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:
1 1/2 in percent = (1 + 1/2) × 100% =
(1 + 0.5) × 100% = 1.5 × 100% = 150%
