An airplane is at an elevation of 35,000 ft when it starts its descent at a 20 degree angle of depression. what is the air distance between the airplane and the airport in miles?

19.4 miles

Step-by-step explanation:

Let x represent distance between the airplane and the airport in miles.

We have been given that an airplane is at an elevation of 35,000 ft when it starts its descent at a 20 degree angle of depression. We are asked to find the distance between the airplane and the airport in miles.

We can see that airplane, airport and angle of depression forms a right triangle with respect to ground. The side of 35,000 ft is opposite side and x is hypotenuse to 20 degree angle.

To convert our distance into miles, we will divide 102333.154 by 5280.

Therefore, the air distance between the airplane and the airport is 19.4 miles.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
