Question

A polar bear starts at the North pole. It travels 1km South, then 1km East, then 1km North to return to its starting point. This trip takes 0.5h. What was the bear's average velocity (in km/h)?​

Answer 1

Answer:

6 km/h

Step-by-step explanation:

A polar bear starts at the North pole. It travels 1km South

Total distance traveled so far: 1 km

then 1km East

Total distance traveled so far: 2 km

then 1km North to return to its starting point.

Total distance traveled so far: 3 km

speed = distance/time

speed = 3 km / 0.5 h

speed = 6 km/h
