10. 9. How far can you get away from your little brother with the squirt gun filled with paint if you can travel at 3 m/s and you have 15s before he sees you?

11. 10. If an animal travels at 60 meters in 30 seconds, what was its speed?

12. Answers: 1.B 2.A 3.B 4.A 5.no motion, constant speed of 0 km/min 6.d = 2 km and t = 10 mins, speed is 2/10 =.2 km/min 7.Contant speed of 12.5 m/s, no acceleration 8.No motion for the first second, constant positive acceleration from 1 sec to 6 second, then a constant speed of 12.5 m/s with no acceleration. 9.d = st and we know s = 3 m/s, t = 15s d = 45 meters 10. 2 m/s
