Math Problem Statement
Ayana and Ashton are in canoes along a stretch of the DesPlaines River. They typically paddle at the same pace and can travel at the same speed as one another (relative to the water). But Ayana heads upstream while Ashton heads downstream. We will define the positive direction as downstream. An observer on the shore observes that Ayana has a velocity of -1.03 m/s and Ashton has a velocity of +2.81 m/s. What is the river velocity? That is, what is the velocity of the water relative to the shore?
