You drive a car 2.0 km to the gas station, 4.0 km to the shopping mall to let your mother off, and 4.5 km back home. the trip takes 20.0 min. what is your average speed? remember distance divided by the time. read the question very carefully and then look at the answer choices very carefully. 0.525 m per s .00875 m/s 4.38 m per s 3.2 m per s

The answer is 0.525 m per s

We would get this by adding up the total distance which was 10.5 and dividing by the total time which is 20 minutes.

answer: a

step-by-step explanation:

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
