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 km/hr and the time of flight increased by 30 minutes. The duration of the flight is:

Answer 1

the duration of the flight be 1 hour

Explanation:

The computation of the duration of the flight is shown below:

Let us assume the duration of the flight be x hours

Now the equation would be

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 hour

hence, the duration of the flight be 1 hour

The same is to be considered
