To find out the speeds of Robin Banks and Officer Willie Katchup, we can use the concept of relative motion. Let's denote the speed of Robin Banks as and the speed of Officer Willie Katchup as . 1. When Robin Banks passes the truck stop, he is 1.5 km away and Officer Willie Katchup hasn't started pursuing him yet. This took place 2 minutes before Willie took off. - At this point, the distance between Robin and Willie is 1.5 km. - This means in 2 minutes, Robin Banks travels a distance of 1.5 km. So, the speed of Robin Banks can be calculated as: 2. After 6 minutes, Robin Banks is 2 km away from the truck stop. Officer Willie Katchup is in pursuit. - This means in 6 minutes, Robin Banks travels a distance of 0.5 km (2 km - 1.5 km). - Since Willie is chasing Robin, we need to consider their combined speed. Willie's speed is . - The relative speed of Robin with respect to Willie is: 3. Seven minutes after Robin passed, Willie was 4 km from the truck stop. - During this time, Willie traveled 4 km from the truck stop. - The distance Robin traveled during this time is 4 km 1.5 km = 5.5 km. - Considering the relative speed from point 2, we can calculate Willie's speed as: Therefore, the speed of Robin Banks is 0.75 km/min, and the speed of Officer Willie Katchup is km/min. tell me without explaining it just the steps
