Question

"Two planes leave the airport at the same time. Plane 1 travels just 9 miles east from

the airport while Plane 2 travels 40 miles north from the airport. What is the diagonal
distance from plane 1 and 2?"

Answer 1

The answer is 41 miles


Imagine the diagonal distance is called c
Using Pythagorean theorem 40^2 + 9^2 = c^2
1600 + 81 = c^2
The square root of 1681 is 41
So c = 41
