Question

The number f of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 80-20x. 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 if each voyage. The ship traveled ___ miles in __ hours. The submarine traveled __ miles in __ hours.

Answer 1

The ship traveled 80 miles in 4 hours while the submarine traveled 75 miles in 5 hours.

How to determine the distance and time traveled?

Based on the information provided, we can logically deduce that the ship is initially 80 miles away from its destination. Thus, f(x) would be equal to 0, if it traveled 80 miles and 0 miles away from its destination:

f(x) = 80 - 20x

0 = 80 - 20x

20x = 80

x = 80/20

x = 4 hours.

By critically observing the graph (see attachment) for the submarine's voyage, we can logically deduce the following:

• Distance = 75 miles.

• Time = 5 hours.
