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 Km/hr And The Time Of Flight Increased By 30 Minutes. The Duration Of The Flight Is?

Answer»

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.
