I’m not sure maybe 81. Sorry if I’m wrong
Answer:
3000
Step-by-step explanation:
1312.50+625+1062.5=3000
It is E X= 22
J LINE SUPPLEMENTARY ANGLE so
the angle is = 180 - (5x-16 ) = 180-5x +16 =196 -5x ( angle in the triangke )
the other angle in the triangle = 50 ( alt interior angles line l parallel m
then we took the triangle sum = 180
<span>196 -5x </span> + 2x +50 = 180
so x = 22
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.
