Question 1191398: Graphing and solving problem.
To boost her immune system, Tina participated a "Bike for a cause". The organizers used a grid to plot the triangular course. Each grid corresponds to 1 km. The starting and ending point is at (3,1). The points (1,3) and (0,0) are the corners of the triangular course, there are water stations to make sure the bikers stay hydrated. What is the total distance traveled by Tina in the whole duration of her biking?
