Might want to take a better picture... it's hard to see.

At this point in time, you can use a technique called cross-mutiplication, where you say that

, and

at this point in time, you can devide each side by 8 and solve
We have to use the following formula which is

Given values of F and m are 7.92 Newtons and 3.6 kilograms .
Substituting these values in the formula, we will get

To solve for a, we have to divide both sides by 3.6 that is

And that's the required answer .
Average rate= change in alt / change in time
r=-378/7=-54ft/min
Answer:
