First, we determine the speed of the ferry by dividing the distance by the time it took to cover that certain distance. speed = (1/6) / (3/7) speed = 7/18 Then, the distance it will travel for an hour is calculated through the procedure below. distance = (7/18hour) x (1 hour) distance = 7/18 Therefore, after an hour, the ferry will be able to travel 7/18 of the distance between two ports.
