Answer:
Motion of the bear:
The motion of the bear is attached in the image given below.
Distance:
The total distance traveled by the bear is:
D = 2 + 4 + 4 + 3 = 13 miles
The time taken by the bear to complete the trip is 4 hours.
Speed:
The speed is given by the formula:
Speed = D/t
On substituting the values, we get,
Speed = 13/4
∴ Speed = 3.25 m/s
