A ship is 80 miles from its home port and is heading at 12 miles per hour. How long until it is 10 miles from its home port. Explain and show work

5.83 hours

Step-by-step explanation:

To find the answer to this problem, first, you need to look at all of the variables.

A ship is moving at 12 miles an hour.

The ship is headed towards its home port 12 miles an hour.

You have to find out how long it will take for the ship to be 10 miles away from the home port. To do this, first, you need to subtract 10 from the 80 miles.

80 (miles) - 10 (miles) = 70 (miles)

This gives you the amount of miles the ship will have to travel to be 10 miles away from its home port.

Now, you have to figure out how long it will take for the ship to travel 70 miles.

Since the ship is traveling at 12 miles per hour, you have to divide 70 (miles) by the speed of the boat (12 miles per hour).

This results in roughly 5.83 hours.

The ship will take 5.83 (or about 6 hours) until it is 10 miles away from its home port.

d

step-by-step explanation:

d

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
