The train left terminal at 11: 20 a. m. and arrive at its destination at 2: 40 p. m. long did the train travel?

Express 2:40 p.m as 14:40 because you can just add 12 hours, like on a 24 hour clock. Then subtract 11:20 from 14:40 to get 3:20.

This is the number of hours traveled, so to find the number of minutes, multiply 3 by 60 then add 20 to get 200 minutes.

∠cbe and ∠deb are same-side interior angles.

i took the test

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
