Two cars are traveling along long straight roads which meet at right angles. Car A starts from a point 120 miles south of the intersection and travels north at a rate of 45 miles per hour. At the same moment car B starts 20 miles west of the intersection and travels west at a rate of 40 miles per hour. At what rate is the distance between the two cars changing 2 hours later
in if you ask questions, the points are taken from your total and given to the one who answered it..
so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
