imagine the pole is a line segment
the line segment is 15ft long
first, find where her left hand is
the amount below her left hand is 2 times the length above
x is the amount above
2x is amount below
total is 15
x+2x=15
3x=15
x=5
2x=10
the segment below her left hand is 10ft while the segment above her left hand is 5ft
right hand is 1.5ft above left hand
how far up is the right hand
the left hand is 10ft up
the right hand is 1.5ft higher, or 10+1.5 or 11.5ft
her right hand is 11.5ft up
