Tue 1/21 1.A coach travels from the station to the beach, a distance of 576km away in 6hrs. The coach is only allowed to travel at a maximum speed of 90km/h. Did the coach break the speed limit?

Wed 1/22 2. A really fast armadillo can cross a road that is 20.00 meters long in 10.0 seconds. What is the speed of the armadillo? AS=D/T AS=20.00m/10.0s AS=2m/s

Wed 1/22 2. A really fast armadillo can cross a road that is 20.00 meters long in 10.0 seconds. What is the speed of the armadillo? AS=D/T AS=20.00m/10.0s AS=2m/s

Thur 1/23 3. Usain Bolt runs the 100m in 9.58 sec. What is his average speed? As = d/t As = 10.44 m/s
