8. Kaplee drove her scooter at an average speed of 15 miles per hour and was 5 miles ahead of Sophia. Sophia drove her scooter at an average speed of 20 miles per hour. This situation can be represented with the system \( y=15 x+5 \) and \( y=20 x \), where \( x \) is the nurmber of hours and is the number of miles from the starting point. After how many hours are kaylee and sophia the same distance from the starting point?

To find when Kaylee and Sophia are at the same distance from the starting point, we can set the two equations equal to each other: \[ 15x + 5 = 20x \] Solving for \( x \): 1. Subtract \( 15x \) from both sides: \[ 5 = 5x \] 2. Divide by 5: \[ x = 1 \] So, they will be the same distance from the starting point after 1 hour. In a fun twist, picture them racing through a park, with Kaylee zooming ahead and Sophia just a little behind but gaining speed—who knew math could be a race? If you're interested in real-world scenarios, think about how GPS systems use similar equations to determine travel times and distances. They constantly compute your speed and distance traveled to give updates on when you'll arrive at your destination.
