Answer:

  30 ft

Step-by-step explanation:

The given scale can be multiplied by a suitable factor to make the corrsponding measurement match known values:

  1 in : 3 ft = (drawing measure) : (actual measure)

Multiplying by 10 makes the drawing measure match the given value:

  10 in : 30 ft = (drawing width) : (actual width)

The actual deck is 30 ft wide.
