In a flight of 600 km, an aircraft was slowed by bad weather. Its average speed was reduced by 200 km/h and the time of flight increased by 30 minutes. The original speed of the aircraft (km/h) is: Form and solve the equation.

Question

Accepted Answer

600. 600/x-200 - 600/x = 1/2. 600(200)/x(x-200) = 1/2, 240000 = x(x-200)/2... 240000*2 = x^2-200x, x^2 -200x -240000 = 0, (x-600)(x+400)=0. x = 600 km/h.
