120 miles in 4.8 hours

75 miles in 5 hours

Step-by-step explanation:

Ship:

The number f(x) of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 25x. This means, initially the ship is 120 miles away from its destination.

If the ship traveled 120 miles, then f(x)=0 (the ship will be 0 miles away from its destination) and

0 = 120 - 25x

25x = 120

x = 4.8 hours.

Submarine:

At x = 0 hours the submarine was 75 miles away

At x = 5 hours, the submarine was 0 miles away.

So, in 5 hours the submarine traveled 75 miles

Answer from: antasia12342

The ship traveled 120 miles in 4.8 hours. The submarine traveled 75 miles in 5 hours.

Step-by-step explanation:

In this case, we just have to use the given graph to answer correctly the submarine voyage. In addition, the given function relates Hours with Distance (miles) about a ship voyage. First, the problem is asking about the time when it traveled 120 miles, and it's asking the distance after traveling 5 hours, to answer that question we just have to see what values belong to each question.

So, the expression f(x) = 120 - 25x specify that the ship is starting from 120 miles away the objective, because when x = 0 (the initial point), y = f(x) = 120. This means that after traveling 120 miles, the ship will be 0 miles away, so f(x) = 0. Replacing this value we will find the needed time to travel 120 miles.

f(x) = 120 - 25x

0= 120 - 25x

25x= 120

$x=\frac{120}{25}=4.8$

Therefore, it will require 4.8 hours to travel 120 miles.

The second question is asking miles traveled after 5 hours by the submarine. In this case, the graph belongs to the submarine. We observe that in x = 5 hours, the distance traveled is 75 miles, because the line dropped from 75 to 0 miles, when went horizontally from 0 to 5 hours, meaning that after 5 hours, it traveled 75 miles.
