Starting from the same place, Ryu walks due west and Samantha walks due east.On the number line, 0 represents their starting point, negative values represent the distance traveled west and positive values represent the distance traveled east. All values are given in feet.A number line with a point for Samantha at coordinate 40 and a point for Ryu at coordinate -160.How many feet apart are Ryu and Samantha on the number line?
Accepted Solution
A:
For Samantha, 2 tick marks east is 120 units east because 1 tick is 60 units. For Ryu, 8 tick marks west is 480 units west because 1 tick is 60 units.They are walking to form a line. Just add their distances from 0. 120 + 480 = 600.--------------------------0----------------------------Ryu: 480 Samantha: 120 480 + 120 = 600.600 units, or feet.
