The fastest train in the Western Hemisphere is the Acela Express. On a route between Boston, Massachusetts, and New Haven, Connecticut, the train regularly travels 135 miles in 60 minutes. What is the speed, in miles per minute, on this portion of the route?

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:

option c

3+x
