Absolute value represents distance. Distances can't be negative.
So it's impossible to have |3-w| be some negative value.
Which is why

has no solutions
Answer:
there is no why to add this
Step-by-step explanation:
If the required difference is 600 mi, lets start of counting by 10s and multiplying the current number
800-700 = 100
1600-1400 = 200
2400-2100 = 300
3200-2800 = 400
4000-3500 = 500
4800-4200 = 600
if 60 hours pass, they will be 600 miles away from each other.
counting by 10 each time will help with problems like or similar to this.
