a plane covered a horizontal distance of 15 miles while following a flight path with a slope of .25. how much altitude did it gain?

To find out how much altitude the plane gained, we can use the concept of slope. The slope of a line is defined as the ratio of the vertical change (altitude) to the horizontal change (distance). In this case, we are given the horizontal distance of 15 miles and the slope of the flight path, which is 0.25.

The slope formula is written as:
slope = (change in altitude) / (change in distance)

To determine the change in altitude, we rearrange the formula:
(change in altitude) = slope * (change in distance)

Plugging in the given values:
(change in altitude) = 0.25 * 15

Therefore, the plane gained:
(change in altitude) = 3.75 miles
