Question

An airplane ascends 160 feet as it flies a horizontal distance of 1,000 feet. How much altitude will it gain as it flies a horizontaldistance of 1 mile? (Hint: 5,280 feet = 1 mile.) Round your answer to the nearest integer.

Answer 1

Distance flying in an horizontal line

Then verttical ascend is 160 feet

because law of proportionality applies

How many feet is 1 mile= 5280

Then now find proportionality between

5280/1000 = 5.28

its the same proportionality between

Ascend/ 160

because vertical proportion= horizontal proportion

Then Ascend should be = 5.28 times 160 = 844.8
