Joe D. Curious is exploring a river with a strong current. He paddles upstream by day taking measurements and readings of water quality going 4 miles a day. He drops an anchor at night, but the current is so strong it still pushes his boat 3 miles downstream each night. His destination is the dam, which is 10 miles upstream from his starting point. If he starts his journey on June 1, when will he reach the dam? It does not take ten days
