We know the rate of the change, 3 meters per hour. And we want to know how long it will take to reach 12 meters. Say we need to reach 6 meters instead 12. How long will that take? 2 hours! Because we divide 6 m by 3 m/h. Now let us do the same thing will 12 meters. 12 m / 3 m/h = 4 hours It will take 4 hours to reach the 12 meters height.
