Question

in a flight of 600 K.m, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced to 200K.m/hr and the time increased by 30 minutes. Find the duration of the flight.​

Answer 1

Answer:

one hour

Step-by-step explanation:

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.
