Final answer:
Sparky will have run 15,750 meters by the time Samantha and Scott meet each other.
Step-by-step explanation:
To calculate the distance Sparky will run, we need to find the time it takes Samantha and Scott to meet each other. Let's start by converting Samantha's walking speed from meters per second to meters per minute. Since there are 60 seconds in a minute, we can multiply 0.875 meters per second by 60 to get 52.5 meters per minute. Now we can determine the time it takes for Samantha and Scott to meet. Let's call this time 't.' Since Scott walks at a speed of 72.5 meters per minute and Samantha walks at a speed of 52.5 meters per minute, the total distance they cover when they meet is 5000 meters. So, we can write an equation: 72.5t + 52.5t = 5000. Solving for 't,' we find that t = 63 minutes. Finally, we can calculate the distance Sparky will run by multiplying Sparky's speed of 250 meters per minute by the time 't.' So, Sparky will run 250 * 63 = 15750 meters.
