Answer:
This method would be an example of a problem-solving strategy called:
B) an algorithm.
Step-by-step explanation:
Algorithms are usually thought of as a mathematical term but, in reality, an algorithm is also a problem-solving strategy used to make decisions, for instance. An algorithm can be defined as a series of steps that will lead to the best decision or to the correct solution to a problem. Algorithms are particularly useful in situations that demand accuracy, even though following the steps may be time consuming. In the passage, Gregory is using an algorithm. He knows the steps the solve the problem related to converting kilometers into miles. It may be a bit time consuming to calculate it, but the answer will be accurate.
