1. Kendra got lost she drove 3 km to west , then 5km north,6km east and 4 km south. and again 3 km west. where is kendra relative to where she started?

also

how do i do these - (-18/12) = i gnore the brackets its there so u no what i mean.

1. You got two directions: east-west, north-south. So take those distances separately.

Call east positive and west negative. 3km west means she travelled -3 in the e/w direction. Later on she went 6 km east which is +6 and then 3 west which is -3, so in the e/w direction she went -3 + 6 - 3 which is ... how far east or west of where she started?

Now do the same thing with the north-south direction, and see where she ends up either north or south of where she started.

Draw a picture, it may well help to understand what's going on here.


I'll let someone else do the fraction question because I can't do the explaining fractions bit any more, my brain burnt out.
