Time and Distance - General Aptitude

Q1:

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:

A 1 hour

B 2 hour

C 3 hour

D 4 hour

ANS:A - 1 hour

Let the duration of the flight be x hours.

Then, 600 - 600 = 200
x x + (1/2)
600 - 1200 = 200
x 2x + 1
 x(2x + 1) = 3  2x2 + x - 3 = 0  (2x + 3)(x - 1) = 0  x = 1 hr.      [neglecting the -ve value of x]
