Question 938248: While canoeing on a river, your paddling speed is twice the river's current. You travel 3 miles downstream and then 3 miles upstream to get back to where you started. [ Write a rule for T(s), the function that gives your total trip time (in hours) as a function of the current's speed s (in miles per hour). The rule should involve a sum of two rational expressions. Carry out the addition to simplify the expression as much as possible. ]
