Han's starting number ------ x , counts backwards by 100
Sally's starting number ----- 300 counts forward by 10
after 6 counts, Sally is 360
after 6 counts, Han's is at x - 600
x - 600 = 360
x = 960
Sally's starting number ----- 300 counts forward by 10
after 6 counts, Sally is 360
after 6 counts, Han's is at x - 600
x - 600 = 360
x = 960
