Answer 1

your correct

Explanation:

Answer 2

That is Correct: 130 miles.

Explanation:

This is a right triangle problem. The pythagorean theorem states that a^2+b^2 = c^2 (hypotenuse)

One side of the triangle is 120 miles (60*2), the other is 50 (50*1).

120^2+50^2 = x^2

16900 = x^2

`√(16900) =√(x)`

130 = x
