A long distance trucker traveled a 180 miles during a snow storm in one direction. The return trip on a rainy day at double the speed it took 3 hours less. Find the speed going

Did you try to figure out how to solve it?
anonymous
  • anonymous
say the speed going is v. say it too time t to reach the destination while going. express v and t in terms of the distance.
anonymous
  • anonymous
took* time t

nikki, we need you to give us some feedback in order to help you.
anonymous
  • anonymous
yeah, solving your math homework is not the point of Openstudy
anonymous
  • anonymous
I did try...I ended up with 2 different variables and cannot solve.
anonymous
  • anonymous
Write down what you got. We can correct you
anonymous
  • anonymous
I got for the return trip 180=2r(t-3)
anonymous
  • anonymous
r is the speed and t is time
anonymous
  • anonymous
right, what is the going trip formula?
anonymous
  • anonymous
180=r(t+3)
anonymous
  • anonymous
I do not know the time to figure out the speed
anonymous
  • anonymous
If im not mistaken the original should be 180 = r* (t)
anonymous
  • anonymous
ok but how do you figure out the time to get the rate?
anonymous
  • anonymous
why did you write 180 = r(t+3)? Does the trucker take 6 extra hours on the way to the destination?
anonymous
  • anonymous
well simplify the second equation
anonymous
  • anonymous
first define what t is.
anonymous
  • anonymous
because I added three hours to the time of the return trip
anonymous
  • anonymous
t is time
anonymous
  • anonymous
define what t is. what do you mean by t?
anonymous
  • anonymous
t is time taken to do what?
anonymous
  • anonymous
the time for the total distance of 180
anonymous
  • anonymous
time for total distance of 180? what does that mean? how can time be for distance?
anonymous
  • anonymous
Nikki, t represents the time of the going trip
anonymous
  • anonymous
What it the time of the going back trip?
anonymous
  • anonymous
it takes t amount of time to go 180 miles on the going trip, and it takes t-3hours on the return trip. im confused on how to find t because i need t to find r
anonymous
  • anonymous
I think this is a classic mechanic problem. So you can use the velocity formula (V=d/t)
anonymous
  • anonymous
right, so it takes t amount of time, going at speed r to reach 180 miles.
anonymous
  • anonymous
so 180 = t*r
anonymous
  • anonymous
That is what I am using i learned it as d=rt which the same thing with only the distance in a different spot
anonymous
  • anonymous
okay while returning, the speed is 2r, and the time take to travel back the same distance reduces by 3 hours. so 180 = 2r(t-3)
anonymous
  • anonymous
yes i have that. but how do you find the speed from that with another variable
anonymous
  • anonymous
so, lets call 180 = tr ------------------------- equation 1 180 = 2r(t-3) ------------------------- equation 2. from equation 1 we have t = 180/r, correct?
anonymous
  • anonymous
yes!!! thank you i got it from here!!! much thanks
anonymous
  • anonymous
so substitute t = 180/r in equation 2 and post what you got.
anonymous
  • anonymous
alright, you are welcome.
anonymous
  • anonymous
30=r
