I don't think anyone can solve this without seeing the table mentioned in the question :)
When grading papers you can convert decimals into percents
Answer:
4/1
Step-by-step explanation:
i believe thats right since 4/1 is a fraction and it can be simplified to 4
Let α represent the acute angle between the horizontal and the straight line from the plane to the station. If the 4-mile measure is the straight-line distance from the plane to the station, then
sin(α) = 3/4
and
cos(α) = √(1 - (3/4)²) = (√7)/4
The distance from the station to the plane is increasing at a rate that is the plane's speed multiplied by the cosine of the angle α. Hence the plane–station distance is increasing at the rate of
(440 mph)×(√7)/4 ≈ 291 mph
