Boat travels 10 mi upstream and 10 mi downstream the stream is moving 1mph and the boat took 5 1/3hrs. What is the speed of boat if the stream still?

Algebra 
PsyDAG,
Distance/time = rate
Let x = speed of boat (rate)
20/(16/3) = (x+1) + (x1)
Assuming your data is correct, solve for x.

Lars,
Rita paddles her canoe upstream at an average speed of 2 miles per hour and downstream at a rate of 3 miles per hour. find Rita's speed in still water and the speed of the river current.
