In this problem it is said that a point a is located at 4, point c is located at 11, and point b lies in between the points a and c.
00:10
We need to determine the location of b such that the ratio of ab to bc is 2 is to 3.
00:15
So let's say that b is located at x.
00:19
So we have that the ratio of ab to bc is 2 is to 3.
00:24
So what is the length of ab? well, a is at 4, b is at x, b lies between the points a and c.
00:33
So b comes after a.
00:35
So the length of ab will be x minus 4.
00:39
Now for bc, c is 11, b is x, and b lies between a and c.
00:44
So b comes before c.
00:46
And so the length of bc will be 11 minus x...
