(a)
Write an equation that relates the distance a golf ball travels at an altitude of 7000 feet y with the distance of sea level x .
(a)

Answer to Problem 28PPS
The equation:
Explanation of Solution
Given:
The distance a golf ball travels at an altitude of 7000 feet varies directly with the distance the ball travels at sea level.
Concept Used:
The golf ball travels at an altitude of 7000 feet is y and the distance of sea level x.
The direct variation equation:
Calculation:
The variation equation:
Graph with the equation
Thus, the relationship is
(b)
Find the average driving distance at 7000 feet if his average driving distance at sea level 180 yards.
(b)

Answer to Problem 28PPS
So, the average driving distance at 7000 feet would be 189 yards.
Explanation of Solution
Given:
The distance a golf ball travels at an altitude of 7000 feet varies directly with the distance the ball travels at sea level.
Concept Used:
The equation:
Calculation:
Now find the average driving distance at 7000 feet if his average driving distance at sea level 180 yards.
The equation:
Thus, the average driving distance at 7000 feet would be 189 yards.
