We have that
<span> [the mean change of altitude]=[change in altitude]/[time]
</span> [the mean change of altitude]=[-370]/[7]---------------> -52.86 ft/minute
the answer is -52.86 ft/minute (<span>the negative sign means that the plane is descending</span>)
(9m - 6)7
Distribute 7 to both sides
63m - 42
Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3
