Use long division - read about it here: http://www.purplemath.com/modules/polydiv2.htm

Good luck!

Answer 2

thank you can you help me with another one? @superdavesuper

Answer 3

Two trains leave a city at the same time and travel in opposite directions.

One of the trains travels at twice the speed of the other.

The trains are 360 miles apart after 2 hours.

What is the speed of the slower train in miles per hour?

Answer 4

idk how to set it up

Answer 5

First step, let speed of slower train be x....so whats the speed for the faster one?

Answer 6

hmm idk..

Answer 7

One of the trains travels at twice the speed of the other.

Answer 8

so thats 2x?

Answer 9

Correct. Now they travel in opposite direction right?

Answer 10

yes

Answer 11

So how far apart will they be after a certain amount of time, say T?

Answer 12

360T

Answer 13

No, please do not jump ahead. Two trains opposite direction, one is x and the other at 2x. So after time T, the distance in between = ( ? + ??) * T right?

Answer 14

i didnt mean to jump ahead, sorry. i just really dont know how to do this

Answer 15

No problem. again - two trains opposite direction, one is x and the other at 2x. So after time T, the distance in between = ( ? + ??) * T

What do u think the ? and ?? should be?

Answer 16

would thet be x+ 2x???

Answer 17

BINGO :) See it is not that difficult

Answer 18

So when T=2 hours, distance=360miles, set up the equation plz

Answer 19

(2 + 2x) * 2 = 360?

Answer 20

Read what u wrote before plz

Answer 21

oh sorry, (x + 2x) * 2 = 360
is that it?

Answer 22

Yup yup n u can solve for x from there!

Good job :)

Answer 23

oh thank you!
