Askydiver jumps out of an airplane after 0.8 second she has fallen 100 feet after 3.1 seconds she has fallen 500 feet emtiaz says that the skydiver should fall about 187.5 feet and 1.5 seconds is his answer reasonable explain

Notice that we can model this situation using a line.

Let the -axis represent the time (seconds) and the -axis the distance the skydiver has fallen (feet).

So, we have the points P1(0.8, 100) and P2(3.1, 500)

We can have the slope of our line using those tow points and the slope formula.

Slope formula:

where

is the slope of the line

are the coordinates of the first point

are the coordinates of the second point

We know form our points that , , , and , so let's replace those values in our slope formula to find :

Now, to find the equation of our line, we are going to use the point-slope formula:

where

is the slope of the line

are the coordinates of the first point

Since we already have the values, let's replace them in our point-slope formula:

Now let's check if Emtiaz's answer is reasonable

Emtiaz says that the skydiver should fall about 187.5 feet and 1.5 seconds. Since represents the seconds in the equation of our line, we just need to replace with 1.5 to find how valid his answer is:

feet

After 1.5 second, the skydiver has fallen 221.7 feet and not 187.5 feet as Emtiaz said. We can conclude that Emtiaz's answer is not reasonable.
