So i see that you need problem, but you need help with this problem.
00:04
The coordinates on the map for san francisco are 53, 17, and those for sacramento are 123 .78.
00:14
Note that the coordinates represent miles.
00:16
Find the distance between the cities to the nearest mile.
00:19
So i'm going to use the distance formula.
00:22
That's the square root of x2 minus x1 squared plus y2 minus y1 squared.
00:30
So we're going to call this x1, y1, x2, y2.
00:36
So i have d equals the square root of x2, which is 123, minus x1, which is 53, which is 53 squared, plus y2, which is 78, minus y1, which is 17 squared.
00:58
And then i have d equals the square root of.
01:01
123 minus 53 is 70 squared plus 78 minus 17 is 61 squared...
