The trail starts at P(−7, 6) and goes to Q(4, 6). It goes from Q to R(4, −6) and then to S(6, −6). What is the total length (in units) of the biking trail?

We know, distance between two points A( p,q) and B(r,s) is given by :

So, distance between P an Q is :

Distance between Q and R is :

Distance between R and S is :

Therefore, total distance is 11 + 12 + 2 = 25 units.

Hence, this is the required solution.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
