How many METs is running at 10.9 mph?

Running at a pace of 10.9 mph is considered a high-intensity activity that corresponds to a significant expenditure of energy. METs, or Metabolic Equivalent of Task, are used to quantify the energy cost of physical activities by comparing it to resting metabolic rates.

At a speed of 10.9 mph, which translates to running at approximately 5.5 minutes per mile, the energy expenditure is typically around 18 METs. This value is drawn from established MET tables that classify various physical activities based on their intensity levels. The calculation incorporates both the speed of the run and the associated energy expenditure seen in vigorous activities.

Given this information, the choice indicating 18 METs accurately reflects the metabolic cost of running at this speed, making it the correct response in the context of this question.
