Final answer:

The ratios with unit rates greater than 1 are 5 miles:1 hour, 9.2 miles:3 hours, 3.7 miles:1 hour, 3.18 mile:2 hours, and 9 miles:3 hours. Ratios with a unit rate less than 1 are not included in the list.

Step-by-step explanation:

To determine which ratios have a unit rate greater than 1, we must calculate the unit rate for each given ratio by dividing the first quantity by the second (assuming the second quantity represents a single unit).

  • 5 miles: 1 hour - The unit rate is already given as 5 miles/hour, which is greater than 1.
  • 14 miles: 3 hours - To find the unit rate, divide 1.75 miles by 3 hours, resulting in approximately 0.583 miles/hour, which is less than 1.
  • 95 miles: 3 hours - To find the unit rate, divide 9.2 miles by 3 hours, resulting in approximately 3.07 miles/hour, which is greater than 1.
  • 37 miles: 1 hour - The unit rate is already given as 3.7 miles/hour, which is greater than 1.
  • 318 mile: 2 hours - To find the unit rate, divide 3.18 miles by 2 hours, resulting in 1.59 miles/hour, which is greater than 1.
  • 9 miles: 3 hours - To find the unit rate, divide 9 miles by 3 hours, resulting in 3 miles/hour, which is greater than 1.

Therefore, the ratios with unit rates greater than 1 are 5 miles:1 hour, 95 miles:3 hours, 37 miles:1 hour, 318 mile:2 hours, and 9 miles:3 hours.
