Answer:

For 3/2 of the speed = 292.5 minutes

For 3/4 of the speed = 146.25 minutes

Step-by-step explanation:

It takes 3hrs 15 minutes to fly from A to B

From A to B = 180minutes + 15 minutes

= 195 minutes (At constant speed)

At constant speed,

If the speed is 3/2 of the original speed,

It will be,

3/2 X (195 minutes) = 585 / 2 = 292.5 minutes

On the other-hand,

If the speed is 3/4 of the original speed,

3/4 X (195 minutes) = 585 / 4 = 146.25 minutes
