Answer:
1386 miles
Step-by-step explanation:
The plane flies ...
(150 mi/h)(1.6 h) = 240 mi
on its first leg. Then it flies ...
(150 mi/h)(9.1 h) = 1365 mi
on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.
c² = 240² +1395² = 1920825
c = √1920825 ≈ 1385.94
The plane is about 1386 miles from its starting point.
