WebThe fundamental equation is that distance = time rate. Suppose that the speed of the boat in still water is s mph and the time it takes to travel the 10 miles upstream is t hours. Travelling upstream is travelling against the current so the going upstream the boat travels at s - 3 mph. Write the fundamental equation above for the trip upstream. WebIn this problem, we will use the formula of distance in terms of velocity and time. d = vt. However, in this problem, we have two unknowns, the speed of the boat and the same time it took to travel 19 miles downstream and 9 miles upstream, therefore we need to equations having the same two unknowns to solve the problem and for that, we will use the …
