Final answer:

To find the skater's average speed in mph, the distance was converted to miles and the time to hours, after which the distance was divided by the time. The calculated average speed was 31.77 mph, which is not among the provided options, indicating potential data or calculation errors.

This correct answer is none of the above.

Step-by-step explanation:

The student asks for the average speed in miles per hour of a skater who completed the men's 1500-meter speed skating event in 1:45.57.

To calculate the average speed, we first convert the distance to miles (1500 meters = 0.932056788 miles) and the time to hours (1:45.57 corresponds to 1.7595 hours). Then, we divide the distance by the time to find the average speed.

  • Convert 1500 meters to miles: 1500 m × 0.000621371 = 0.932056788 miles
  • Convert time to hours: 105.57 seconds / 3600 = 0.029326944 hours
  • Calculate average speed: 0.932056788 miles / 0.029326944 hours = 31.77 mph

Since this answer does not match any of the provided options, it's possible there was a misinterpretation of the data or units given in the question.

This correct answer is none of the above.
