Two​ high-speed ferries leave at the same time from a city to go to the same island. the first​ ferry, the​ cat, travels at 30 miles per hour. the second​ ferry, the​ bird, travels at 24 miles per hour. in how many hours will the two ferries be 6 miles​ apart?

1 hour

Explanation:

Since the definition of velocity is , we can calculate the position at time t of an object moving at speed v with .

The position of the first ferry is

The position of the second ferry is

We want to know when they will be 6 miles apart. This means, if we call that distance d, that we want to know when the difference between their positions will be d, or (we know that at the beginning the position of the ferry 1 is of higher value than that of ferry 2 since it left before).

We use our previous formulas then:

Since we want the time, we do:

And substitute our values:
