Answer:
Step-by-step explanation:
240 yards per hour is 720 feet per hourto convert hours to seconds, divide 720 feet by 3600 seconds per hour to get0.2 feet/foot per secondOR1/5 feet/foot per second
3tenths because 5tenths=50 And 2tenths=20 so if you do 50-20 you will get 30 or if u do 20+30 you will get 50 so either way is fine
