The first one is 135 per hour if you barely went 90 miles in a hour in a half, and the second one it is 1/3+1/3+1/3 you add 2 more thirds so it means you add 2 forths 1/4/+1/4+1/4=3/4 so you paint 3/4's of the wall

We need to find thr rate of change (slope) of the line joining these two points ~





Slope of the line (m) joining the two points is 2 ~
If I'm reading this right, than all 9 angles are acute?
