Answer: The actual ship is 168 in by 390 in
Explanation:
The model ship is:
28 in by 65 in.
The factor of scale is 1/2 ft, this means that each inch corresponds to 1/2 ft, so we have that the actual scale is:
28 in*(1/2 ft/in) = 28*(1/2)ft = 14ft
by:
65in*(1/2ft/in) = 32.5ft
So the ship is 14ft by 32.5 ft, and knowing that 1 ft = 12 inches, we can write this in inches as:
14*12 in = 168 in
32.5*12 in = 390in.
The actual ship is 168 in by 390 in
