bleh no help to me ><
I need to know how to do this problem:
A tourist walks n km at 4km/h and then travels 2n km at 36km/h by bus. Express the toal traveling time in t (in hours) as a funciton of n.
i hate these things

i hate these things
f(n) = (1/4)n + (1/36)n * 2
f(n) = (9/36)n + (2/36)n
f(n) = (11/36)n
f(18)=(11/36)18
f(18)= 5.5 hours
18km @ 4km/hr = 4.5 hours
36km @ 36km/hr = 1 hour
4.5 + 1 = 5.5
right ?

back of the book says
11n/36 = t
11n/36 = t

is it right? it has been a while. what i tried was.....
(walk time) + (bus time) = total time
Walk time = Nkm * 1hr/4km (the km cross each other out and you are left with hours)
bus time = 2nkm * 1hr/36km
leads you to
n/4 + 2n/36= t
or
n/4 + n/18=t
common denominator.......
18n/72 + 4n/72=t
22n/72=t
11n/36=t
i would try that out before usign it (make n = a random number and see if it works out)
(walk time) + (bus time) = total time
Walk time = Nkm * 1hr/4km (the km cross each other out and you are left with hours)
bus time = 2nkm * 1hr/36km
leads you to
n/4 + 2n/36= t
or
n/4 + n/18=t

18n/72 + 4n/72=t

18*(11/36)
18*.3055555555555555555555555 etc
5.5
(18*11)/36
198/36
5.5
18*.3055555555555555555555555 etc
5.5
(18*11)/36
198/36
5.5

1.a store owner bought n dozen toy boats at a cost of $3.00 per dozen and sold them for .75 apiece. Express the profit P in dollars as a fucntion of n
2.the height of a cylinder is twice the diameter. express the total surface area A as a function of height h
thanks guys this helps alot i need to study for a exam later this week and this shit is most of the stuff on it
