Calculate the boat’s speed and the time required to travel downstream based on information about the boat traveling upstream in a river with a current.
River Route
So
When a boat travels upstream
It took.
The river’s current speed is
Therefore,
How long does it take to travel downstream?
Upstream Speed  
Speed in still water  
Downstream Speed  
Time to travel downstream 
(1) Speed of the boat traveling upstream = Distance traveled upstream ÷ Time taken to travel upstream
(2) Speed of the boat in still water = Speed of the boat traveling upstream + River current speed
(3) Downstream speed of the boat = Speed of the boat in still water + River current speed
(4) Downstream time = Distance traveled on the river ÷ Downstream speed of the boat
