Runner and Walker Problem Analysis

The video tutorial explains a problem where a runner and a walker start at the same point on a quarter-mile track and move in opposite directions. The runner runs at 9 mph, and the walker walks at 3 mph. The tutorial uses the formula distance equals rate times time to find the time it takes for them to meet, which is calculated in hours and then converted to seconds. The final result is that they meet after 75 seconds.

What is the initial setup of the problem involving the runner and walker?

• They start at different points on a half-mile track.

• They start at the same point on a quarter-mile track.

• They start at the same point on a half-mile track.

• They start at different points on a quarter-mile track.

At what combined rate do the runner and walker move apart from each other?

• 15 miles per hour

• 6 miles per hour

• 9 miles per hour

• 12 miles per hour
