The time it takes for a race car to finish a lap (to the nearest tenth of a second) is represented by the variable t. Which set of numbers best describes the value of t?

The variable t, representing the time it takes for a race car to finish a lap, is best described by a set of positive real numbers, as lap times cannot be negative or zero. Typically, lap times are measured in seconds and often fall within a range that can include decimal values, reflecting tenths or hundredths of a second for precision. Thus, a suitable set for t would be the interval of positive real numbers (0, ∞).
