Final Answer:
The total number of revolutions the engine makes depends on the given time and RPM data, which needs to be provided for an accurate calculation. Thus, the correct answer is option c.
Step-by-step explanation:
The total number of revolutions a engine makes is determined by the product of the time it operates and its revolutions per minute (RPM). For instance, if the engine runs for 10 minutes at 60 RPM, the calculation would be 10 minutes × 60 revolutions per minute = 600 revolutions (option c).
Without the specific time and RPM data provided, it's impossible to determine the total number of revolutions accurately. To arrive at the correct answer, the time duration for which the engine operates and the RPM at which it functions during that period must be known. Once these values are given, the calculation is straightforward, multiplying the time by the RPM to find the total revolutions.
Therefore, to arrive at a definitive answer among the options provided (400, 500, 600, 700 revolutions), the precise values of time and RPM need to be given in the question or problem statement. Without this information, any of the listed values could potentially be the correct answer depending on the specific data provided.
