Problem
A boat going upstream takes 1.5 times longer than going the same distance downstream. If the water current in the river is 8 kph, calculate the speed of the boat in still water.
| A. 30 kph | C. 40 kph |
| B. 50 kph | D. 20 kph |
Speed of the Water Current
Problem
In still water, your small boat averages 8 miles per hour. It takes you the same amount of time to travel 15 miles downstream, with the current, as 9 miles upstream, against the current. What is the rate of water's current?
| A. 4 miles/hr | C. 2 miles/hr |
| B. 3 miles/hr | D. 5 miles/hr |
