Question

in a flight of 600 km an aircraft was slowed down due to bad weather its average speed for the trip was reduced by 200 kilometre per hour and the time increased by 30 minutes find the duration of the flight​

Answer 1

Answer:

Step-by-step explanation:

The duration of the flight is 1 hour

Let the duration of the flight be x hours.

Then,600/x-600/x + (1/2)= 200

        600/x-1200/2x + 1= 200 

        x(2x + 1) = 3

        2x² + x - 3 = 0

       (2x + 3)(x - 1) = 0 

        x = 1 hr.
