Q:

2) Flying with the wind a plane went 183 km/h. Flying into the same wind the plane only went 141 km/h.Find the speed of the plane in still air and the speed of the wind.

Accepted Solution

A:
Answer:Speed of plane in still air = 162 km/h Β  Speed of wind = 21 km/h Step-by-step explanation:Flying with the wind a plane went 183 km/h. Flying into the same wind the plane only went 141km/h. Find the speed of the plane in still air and the speed of the wind. Β ================= Let plane speed in still are be "p". Let wind speed be "w" ------------------ Equations: p + w = 183 km/h p - w = 141 km/h ----------------- Add and solve for "p": 2p = 323 plane speed in still air = 161.5 km/hr ------ Solve for "w": p + w = 183 161.5 + w = 183 wind speed = 21.5 km/hr
