If T were to scatters the leaves faster than H rakes them, H would Neve finish raking. So must be over 20 minutes
1/15-1/T=1/20

T=60 mins
So it would take Trudy 60 minutes to scatter all of the leaves
Sorry but there is no question

Answer:
25%
Step-by-step explanation:
Given data
Last years shipment= 37220 lamps
These years shipment= 29776 lamps
% Decrease= Initial-Final/Initial*100
% Decrease= 37220-29776/29776*100
% Decrease= 7444/29776*100
% Decrease= 0.25*100
% Decrease= 25%
Hence the decrease is 25%
