What we need to do is divide 18 by 8 because 18 cups of flour makes 8 loaves of bread. By using a calculator, 18/8 = 2 1/4.
Here is the set up:
(1/4)/2 = (9/4)/y
Solve for y.
Step-by-step explanation:
(2.6 X 10⁵)²
=6.76×10¹⁰
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
