Question

Starting from the same place, Ryu walks due west and Samantha walks due east.

Answer 1

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.

Ryu: 480                         Samantha: 120

         480              +             120           =    600.

600 units, or feet.
