40% * 150 =
= 40/100 * 150 =
= 4/10 * 150 =
= 2/5 * 150 =
= 2/1 * 30 =
= 2 * 30 =
= 60
1.2 Inches, It moves 0.3 inches in 1 hour so if in 1 hour it moves 0.3 and in 2 0.6 and in 3 0.9 so in 4 hours it will move 1.2 inches
4/7 = 8/14 = 12/21 = 16/28, etc
Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.
Hope this helps :)
