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
4/60-1/T=3/60
T=60 mins
So it would take Trudy 60 minutes to scatter all of the leaves
Answer:
3/4=0.75
4/5=0.8
7/10=0.7
0.75+0.8=1.55
1.55-0.7=0.85

So what they need to rais is what the school doesn't give them
so to find that subtract what the school gives them from how much they need
need=680
given=130
680-130=550
they need to raise 550
if each member raises the same amount we fid that by doing
total divided by number of members
total=550
number o fmembers=50
550/50=11
each must raise $11
