Answer:
4.5
Step-by-step explanation:
Probably too late for your RSM homework, but here is the solution:
6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]
Simplify to 54/(x(9-x))=8/3
Cross multiply: 162=(8x)(9-x)
Simplify -x^2+9x=20.25
Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0
Solve and get 4.5 :D!
