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:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
