Answer:
3.1 because you round the numbers to the nearest .1 spot if its .5 or above then it goes to the next whole number

1 . when will the fare reach that height:</span>
<span>The ascending and descending time are equal but let's show
it: set the h = 0 </span>
<span>
1500t - 16t^2 = 0 => solve the quadratic </span>
<span>
t = 0 => reject </span>
<span>
t = 375/4 seconds => period to hit the ground, notice that this is twice the
time to reach max h. </span>
2. If the plane … solution:
<span>d = vt </span>
<span>
t = d/v </span>
<span>
= 50,000/880 </span>
<span>
It is approximately 56.8 sec to reach the flare but the flare reached max h at
375/8 ≈ 46.9 sec, so it won't hit the plane going up, but will it hit the plane
on its way down from 35,156.25 ft.</span>
