Grace in her family live in chicago. for vacation they decided to drive to atlanta and then to dallas. it is 722 miles from chicago to atlanta in 800 miles from atlanta to dallas. the family's average driving speed was 49 miles per hour. estimate the number of hours of driving time their trip took from chicago to dallas took.

good luck on ur quiz test or homework. have a good day : )

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
