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 number 8 would be its simplest form.<span />
Compare or
order the digits that are different, Write > or <. or use a number line
<span>44 < 72<span>
Say:
</span>"44 is less
than 72"</span>
<span>Or you
can look at the place value.</span>
<span>You can express using an exponent, an octet and many more</span>
i'm not sure how to solve the first one but the second is 150
B) the values will create a line with positive slope when graphed on a scatter plot.
