Imagine this scene: Yolanda embarks on a journey from point X to Y, while Bob begins his walk in the opposite direction, from Y to X, an hour later. The distance between them covers 45 miles. Yolanda walks at a steady pace of 3 miles per hour, while Bob walks at a brisk pace of 4 miles per hour. The question that arises is: how many miles had Bob walked when they finally met?
This is the time to apply our problem-solving skills. We must carefully analyze the situation and develop a strategy to discover the answer.
Let's see it step by step. Suppose t represents the number of hours Bob had walked when he met Yolanda. At that time, Bob had traveled 4t miles, while Yolanda, having walked for an hour more, had traveled 3(t + 1) miles. Together, their distances should add up to a total distance of 45 miles.
Now, armed with this equation, we embark on our search for the solution:
4t + 3(t + 1) = 45
Expanding and simplifying, we find:
7t + 3 = 45
7t = 42
Solving for t, we find that t is equal to 6 hours. Therefore, when they met, Bob had traveled 4t miles, which is equivalent to 4 multiplied by 6, resulting in 24 miles.
Confidently, we concluded that Bob had walked 24 miles when they crossed paths. The right answer? A resounding option A.
