If you walk at an average speed of 5 km/h for 30 minutes, how far will you walk? Show your work

Let t be time (in hours), d be distance (in km) and s be speed (in km/h). Notation: let W be walk and R be run. Distance is speed * time.

t(total) = t(W) + t(R)

1 = t(W) + t(R)

1-t(W) = t(R)

d(total) = d(W) + d(R)

4 = s(W)*t(W) + s(R)*t(R)

4 = 3*t(W) + 5(1-t(W))

4 = 3*t(W) + 5 - 5*t(W)

group like terms

-1 = -2*t(W)

t(W) = 0.5 hr

Since he walks 3 km/h, he walked 1.5 km.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
