Answer:
22.5
Explanation:
My weight = 100 pounds
Sister's weight = 150
Distance from fulcrum = 15 ft
Distance has an inverse proportion with weight
Distance = k/w
Where k is a constant
K = distance x weight
K = 100 x distance
150 x 15 = 100 distance
2250 = 100 distance
Divide through by 100 to get distance
2250/100 = distance
Distance = 22.5
