The length of Philip's stride when walking is 4 inches greater than the length of Anne's stride. If it takes Philip 5 steps and Anne 6 steps to walk the same distance, what is the length of Anne's stride?

20

Step-by-step explanation:

Let :

Length of Anne's stride = x

Length of Phillips stride = x + 4

Number of steps taken to walk same distance :

Anne = 6 steps ; Philips = 5 steps

Distance moved = Length of stride * number of strides

Hence,

For same distance :

Anne's distance = Phillip's distance

x * 6 = (x + 4) * 5

6x = 5x + 20

6x - 5x = 20

x = 20

Length of Anne's stride = 20

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
