PLS HURRY The number f of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 30x. The number f of miles a submarine is from its destination x hours after leaving port is shown in the graph below. State the distance and length of time of each voyage.
Submarine Voyage

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

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

only 2 outcomes have passed the given condition.
