Answer: 440 ft
Explanation:
The top walking deck is 120ft long and yet comprises only 3/11 of the ships total length.
Assuming the total length of the ship is x ft long, the expression would therefore be:
x * 3/11 = 120 ft
The above shows that if x is multiplied by 3/11 it will give a distance of 120ft which is the top walking deck length.
Solving for x:
x * 3/11 = 120
x = 120 ÷ 3/11
x = 120 * 11/3
x = 440 ft
Note: When being divided by a fraction, you can multiply the inverse of the fraction to find the result.
