Question

A polar bear starts at the North Pole. It travels 1.0km east, then 1.0km north, then 1.0 km west to return to its starting point. This trip takes 45 min. What was the bears average speed?

Answer 1

Total distance travelled = 1 + 1 + 1

= 3 km

Total time taken = 45 min

= $\frac{45}{60}$ hours

= $\frac{3}{4}$ hours

Average speed = $\frac{Distance}{Time}$

= 3 ÷ $\frac{3}{4}$

= 3 x $\frac{4}{3}$

= 4 km/hr

So, the bears average speed was 4 km/hr

Answer 2

Answer:

here is your  answer mate!!

Explanation:

Total distance travelled = 1 + 1 + 1

= 3 km

Total time taken = 45 min

=  45/60 hours

= 3/4 hours

Average speed =  distance/time

= 3 ÷  3/4

= 3 x  4/3

= 4 km/hr
