First, we need to convert the scale ratio from inches to feet. Since 1 foot is equal to 12 inches, we can divide both sides of the ratio by 12 to convert inches to feet:
5 inches : 2 feet
(5 inches) / (12 inches/foot) : (2 feet) = 5/12 feet : 2 feet
Now we can set up a proportion to find the actual width of the gym:
(5/12 feet) / 170 inches = X feet / 1
X = (5/12 feet) * (1 / 170 inches)
X = 5/2040 feet
X = 0.00245 feet
So the actual width of the gym is approximately 0.00245 feet.
5 inches : 2 feet
(5 inches) / (12 inches/foot) : (2 feet) = 5/12 feet : 2 feet
Now we can set up a proportion to find the actual width of the gym:
(5/12 feet) / 170 inches = X feet / 1
X = (5/12 feet) * (1 / 170 inches)
X = 5/2040 feet
X = 0.00245 feet
So the actual width of the gym is approximately 0.00245 feet.

Apologies for the confusion. Let's redo the calculation correctly.
The scale ratio is 5 inches : 2 feet.
To convert 170 inches to feet, we divide by 12 (since there are 12 inches in a foot):
170 inches / 12 = 14.17 feet (rounded to two decimal places)
Now, we can set up a proportion to find the actual width of the gym:
5 inches / 2 feet = 170 inches / X feet
Cross multiplying gives us:
5 inches * X feet = 2 feet * 170 inches
Simplifying, we get:
5X = 340
Dividing both sides by 5:
X = 68
Therefore, the actual width of the gym is 68 feet.
