If the goat is starting at post #1, there is 2.5m * 4 to the 5th post = 10m.
Velocity = 10m/9s = ?
From 5th to 11th post = 2.5m * 6 = 15 m
Velocity = 15m/11.5s = ??
Average velocity = (? + ??)/2 = ???
Fence posts around a pasture are 2.5 m apart. A goat starts running west beside the fence. When it passes the fifth post, 9.0 s have elapsed. It passes the eleventh post at 11.5 s. What is the goat’s average velocity?
