Final answer:
Sam has already traveled 50 miles according to the question. To find the average speed, divide the distance by the time. The answer with further illustrative examples involving distance and average speed calculations has been provided to help understand the concepts.
Step-by-step explanation:
The question involves finding the distance traveled by Sam who travels 50 miles in 7 hours. However, since you provided the distance already, there may be a misunderstanding in the question. If the task is to calculate the average speed, you would divide the distance by the time. So, if Sam actually needs to calculate the average speed of his journey, it would be:
50 miles ÷ 7 hours = approximately 7.14 miles per hour.
If Sam's question is indeed about the distance he traveled, then the answer is clearly stated in the question as 50 miles. However, if you are looking for an example involving both distance and average speed, here's one:
Suppose a train travels 40 miles one way and 40 miles back, the total distance traveled would be 80 miles. If the train took 4 hours for the round trip, then the average speed would be calculated as:
80 miles ÷ 4 hours = 20 miles per hour.
