lizzy is tiling a kitchen floor for the first time she had a tough time at first and placed only 5 tiles the first day she start
ed to go faster and by the end of day 4 she had placed 35 tiles she worked at a steady rate after the first day use an equation in point slope form to determine how many days lizzy took to place all of the 100 tiles needed to finish the floor
She placed only 5 tiles the first day and started to go faster and by theend of day 4 she had placed 35 tiles. So, we have two points: (1,5) and (4,35) Slope = 30/3 = 10 Y - 5 = m(X - 1) For 100 tiles, 100 - 35 = 10 (X - 4) 65 =10(X - 4) 6.5 = X - 4 X = 10.5 So,11th day
Let's assume that the faster car has a 2 mile "head start". The faster car is 1.2 times faster (48/40) than the slower car. It will take five 2 mile trips to "catch" the other car. Five 2 mile trips will take 5 * 40 seconds = 200 seconds.
