Answer:
use the pythagorean theorem
Step-by-step explanation:
So.... notice the picture below
we know when y = 140 and x = 240, r = 250
so let's use the pythagorean theorem

now... how much time does the controller have? well, say, plane "y" is going at dy/dt of 140mph, and is 70 miles away, 140 is 2*70, so it can cover those 70 miles in 1/2 hr, and when it does, it'll collide with the other,
so, the controller has that much, less than 1/2 hr
Answer:
You can recognize that .25 is 1/4, so 0.625 is 1/4 of the way
from 0.6 to 0.7
Simply change 1/4 to a decimal
1/4 = 0.25
now we can multiply 0.25 and 32
lets do the math:)
0.25 x 32 = 8
your answer = 8
