This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone

Answer:
okay gonna assume the dilation scale factor is 0.5, not -0.5
A' is at point (2,1)
B' is at point (3,1)
C' is at point (3,2)
D' is at point (2,3)
Step-by-step explanation:
make all of the sides of the model smaller by multiplying by 0.5. Then keep point A' where point A is because the center of the dilation is at point A.
