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)?

Total distance travelled = 1 + 1 + 1

= 3 km

Total time taken = 45 min

=  hours

=  hours

Average speed =  

= 3 ÷  

= 3 x  

= 4 km/hr

So, the bears average speed was 4 km/hr

0

Step-by-step explanation:

The polar bear's net distance traveled is 0 km since it ends up at the same point it started.

velocity = 0 km / 0.5 h = 0

0
