To understand the question, we must first recognize that the relationship between workout hours and calories burned is proportional. Looking at the table:
[tex]\[
\begin{tabular}{|l|l|l|l|}
\hline Workout (hours) & 1 & 2 & 3 \\
\hline Calories Burned & 320 & 640 & 960 \\
\hline
\end{tabular}
\][/tex]
Notice that when the number of workout hours increases, the number of calories burned increases proportionally. Specifically:
- For 1 hour of workout, 320 calories are burned.
- For 2 hours of workout, 640 calories are burned.
- For 3 hours of workout, 960 calories are burned.
Next, consider the descriptions provided:
1. The number of hours working out is dependent on the number of calories burned. For a one-hour workout, there are 320 calories burned, and for a two-hour workout, there are 640 calories burned.
2. The number of hours working out is dependent on the number of calories burned. For every 320-hour workout, there is 1 calorie burned, and for every 640-hour workout, there are 2 calories burned.
3. The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 320 calories burned, and for a two-hour workout, there are 640 calories burned.
4. The number of calories burned is dependent on the number of hours working out. For every 320-hour workout, there is 1 calorie burned, and for every 640-hour workout, there are 2 calories burned.
- The first option isn't a correct description since it incorrectly suggests calories burned dictates workout hours.
- The second option contains an impossible scenario describing 320-hour and 640-hour workouts, which doesn't match reality.
- The third option makes sense as it correctly describes that the number of calories burned depends on workout hours, with specific examples matching actual data.
- The fourth option contains the same inconsistency as the second and is not plausible.
Hence, the correct description in words is:
The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 320 calories burned, and for a two-hour workout, there are 640 calories burned.
Therefore, the detailed solution concludes that the correct description in words is the one corresponding to the third option in the list.
