Final answer:
In the expression ‘t=time spent commuting to work in minutes,’ the variable t represents the time spent commuting to work in minutes. (option c is the correct answer).
Step-by-step explanation:
In the expression t=time spent commuting to work in minutes, the variable t represents the time spent commuting to work in minutes. This is an option (c).
The other options, such as distance traveled (option a), amount of money spent (option b), and calories burned (option d), do not match the definition provided for the variable t. In different contexts such as velocity equations or analyzing commute times, the variable t plays a crucial role in determining other factors like speed, or in graphing position versus time.
The variable t represents the time spent commuting to work in minutes, and this interpretation is consistent with mathematical conventions. It reflects a straightforward correspondence between the variable and its real-world significance in the context of the equation.
