Yes

find a round trip flying time
anonymous
  • anonymous
How do I start?
amistre64
  • amistre64
im gonna say you can start by calling your variables to and from .. t and f
amistre64
  • amistre64
you know the total distance is going to be twice the distance stated right?

I got 138,430/59r

  • anonymous
But all I need to do is show my work and I can get an A
amistre64
  • amistre64
one direction is 18% faster t + f = 2(1270) t + ( t + t(18%)) = 2540 t + t + .18t = 2540 2.18t = 2540
amistre64
  • amistre64
the "format" in the book is just confusing to read, you need to be able to parse the instructions from the clutter
amistre64
  • amistre64
also, keep in mind the speed = distance/time
anonymous
  • anonymous
Ok, but how would i do this.. d/t=s 1270/1165.137615
amistre64
  • amistre64
d from At-Al = 1270mi speed Al-At = 18% speed from At-Al r = speed from At-Al in m/h find time for a round trip ----------------------------- r = 1270mi/t hours k = 1270mi/t hours, times (1.18) round trip time = r + k thats the best i got ..... solve for t?
anonymous
  • anonymous
ok
anonymous
  • anonymous
So was mine right?
amistre64
  • amistre64
s = d/t t = d/s 18% of t is equal to 18% of d/s a little adjusting ...\[t=\frac{1270}{s}+\frac{1270(1.18)}{s}\] \[t=\frac{1270(2.18)}{s}\] without knowing an actual speed or time value ... this is what we would be left with

  • anonymous
So we can't solve?
amistre64
  • amistre64
it asks for a simplified expression, not for a numerical solution
anonymous
  • anonymous
But in the basck of my book it says the answer is 138,430/59r
amistre64
  • amistre64
the "r" is how they are formating it to their own delusions :)
anonymous
  • anonymous
ok then how do they get the actual number?
amistre64
  • amistre64
the trip to is given as: r = 1270/t; or t = 1270/r the trip back is 18% faster: r + r(.18) adding the 2 speeds gives us a round trip speed r + (r + r(.18)) 1270 + 1270 + 1270(.18) ------------------------- t 1270 + 1270 + 1270(.18) ------------------------- 1270/r 1270(2.18) ---------- = 2.18r 1270/r not really sure how the back of the book is trying to get at it, or even if the book is correct
