Answer:
1) 2.5 m/s 2) 37.5 meters
Step-by-step explanation:
kilometers to meters is 1000 meters. take 9000 meters per hour and divide by 60 which equals 950 meters per minute (60 minutes per hour). take that number and divide it by 60 as well (60 seconds per minute) which equals 2.5 meters for every second which is the answer to question one. now that we know how many meters per second just multiply by 15 to get how many meters in 15 seconds. (2.5 * 15) or 37.5 meters
