1. The problem statement, all variables and given/known data A boat is sailing starting from x = 200m. When interpreting x(position) vs. t(time) graph for this boat with math models x = -20t + 200(t<=10), Is it right to say "The boat is approaching to the origin" ? (When t <= 10) 2. Relevant equations x = -20t + 200(t<=10) 3. The attempt at a solution I thought it would be yes, but wasn't sure why. What if the boat is moving diagonally? not directly to the origin?
