Answer is 7/18.
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.
Answer:
15 hours
Step-by-step explanation:
We can use the formula below to solve this:
Where
t is the time taken for BOTH to fill up the pool [6 hours]
a is the time taken by first tap [10 hours]
b is the time taken by second tap [we need to find this]
Now putting in all the into and solving for y, we get:
Hence, its gonna take 15 hours for the second tap to fill the pool alone.
