A ferry traveled 1/6 of the distance between two ports in 3/7 hour at this rate what fraction of the distance between the two po
Masja [62]
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.

To find out how much she spent during the second month, all we have to do is subtract $305.43 and $213.20

$305.43 - $213.20 = $92.23

Therefore she spent $92.23 during the second month
