How do you find direct variation? im having trouble understanding this subject
rodikova [14]
I was too just a couple of weeks ago. So direct variation is the constant way to variables change together. EX: 
x  y
1 2
2 4
3 6
Direct variation must be in the format b=ka where k is a constant. So the direct variation here could be y=2x. Understand?

Two trains leave towns 471 miles apart at the same time and travel toward each other. One train travels 21 miles per hour slower
nadya68 [22]

Let the slower train's velocity be x-21

Let the faster train's velocity be x

We know that the approach speed is the sum of both speeds, so x+x -21= 2x-21.

The approach rate is given by Distance/time = 471/3 = 157mpH

x+x-21=157

2x=157+21

2x=178

x=89mph

The slower train is travelling 89-21 = 68mph

The faster train is travelling 89mph.
