Given:
altitude, x = 1 mile
speed, v = 560 mi/h
distance from the station, x = 4 mi
Solution:
To find the rate,
Now, from the right angle triangle in fig 1.
Applying pythagoras theorem:
differentiating the above eqn w.r.t 't' :
(1)
Now, putting values in eqn (1):
The rate at which distance from plane to station is increasing is:
The solution to the problem is as follows:
Normal force is m*g plus 240 N*sin30.
<span>30 kg*9.8 m/s^2 + 240 N*sin30 = 414 N

Answer:
Before we begin, first convert the minutes unit to seconds to match the unit for speed. Since there are 60 seconds in a minute, and there are 3 minutes, 3*60 = 180 seconds. Using the formula s = d/t, we can manipulate this formula to solve for d, the distance. So we isolate the d variable, to get d = st, and we can substitute the values of s and t into this formula. Now we have d = 4m/s*180s. Now we solve this to get d = 720m. Now we can convert meters to miles, to get approximately 0.45 miles.

Explanation:
To do this, one uses a conversion factor. In mathematics, specifically algebra, a conversion factor is used to convert a measured quantity to a different unit of measure without changing the relative amount. To accomplish this, a ratio ( fraction ) is established that equals one (1).
