Melissa drew a scale drawing of a city. A neighborhood park is 36 inches wide in the drawing. The actual park is 60 yards wide. What is the scale of the drawing?

Since one yard is equal to 36 inches, the width of the actual park is 60 yards * 36 inches/yard = <<60*36=2160>>2160 inches.

The scale of the drawing is 36 inches / 2160 inches = 1/60. Answer: \boxed{\frac{1}{60}}.
