Flying against the wind, an airplane travels 3760 kilometers in 4 hours. Flying with the wind, the same plane travels 4320 kilometers in 3 hours. What is the rate of the plane in still air and what is the rate of the wind?

1 hour each 30 minutes so the answer is 30 minutes

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
