If an airplane starts at point R and travels 14 miles directly north to S, then 48 miles directly east to T, what is the straight-line distance (in miles) from T to R?
(a) 25 (b) 34 (c) 50 (d) 2500

Read Solution (Total 1)

Note that the path of the airplane and the straight-line distance between S and T form a right triangle where the distance traveled north and distance traveled east are the two legs.

By using the Pythagorean Theorem, we see that, if c is the straight-line distance, then:
c^2 = 14^2 + 48^2 ==> c = √(14^2 + 48^2) = 50 miles.
