This one is . . . (13 lbs)/(5/8 lbs / bag) = 13*8/5 = 104/5 = 20 4/5
We need to convert 45 min to hours.
There are 60 min in an hour.
45/60 = 0.75
45 minutes = 0.75 hour
(4 km)/(0.75 h) = 5.3333 km/h = 5 1/3 km/h
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y
she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve
we have
180=3x+2y and
x=15+y
subsitute 15+y for x
180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y
solve for x
x=15+y
x=15+27
x=42
she spent $42 on each sister
