Answer 1

has less wind resistance

Answer 2

do you know where to start?

Answer 3

@Jlynn89 I'm trying to figure out where you need help how far have you gotten?

Answer 4

I don't even know how to start it.

Answer 5

okay no worries. The key to problems like this is to let one of the things you are trying to find be "x"

Answer 6

so we will let the slower speed be x for us

Answer 7

can you write the faster speed in terms of x?

Answer 8

I do not know what you mean by that. The "terms of x" bit

Answer 9

this is not the correct anwer for writing the faster speed in terms of x but it should explain what I mean by in terms of x:
faster = x +5

Answer 10

let me put it this way how much faster is the good weather speed compared to the bad weather speed?

Answer 11

Oh okay got you.

Answer 12

so what did you get?

Answer 13

What you meant by terms of x, I didn't see you had writen something else. Sorry I am really crap at this section.

Answer 14

well I mean what did you get when you wrote the faster speed in terms of x? I did not give you the correct answer above

Answer 15

" truck tralvels 15km/hr faster"

Answer 16

Ok I set it up like what is in the picture

then did

14x= 10.5 (x+75)
then distributed

14x= 10.5x+157.5

subtracted 10.5 from itself and tehn from 14

3.5x=157.5

divide 3.5 on both sides

and ended up with x= 45

x=45
x+15 ended up being 45+15 and got 60

Answer 17

seems right to me :)

Answer 18

lol thank you! I get really confused with this ;_;

Answer 19

not a problem just always remember to see if you can rewrite one of the numbers you are looking for in terms of the other number you are looking for
