The answer is 2.6 m/s

The speed (v) is distance (d) through time (t).
v = d/t

We know:
d = 390 m
t = 150 s

v = d/t
v = 390 m / 150s
v = = 2.6 m/s

If a polar bear were to swim 390 meters in 150 seconds, that would mean we have to divide 390 by 150.
The polar bear can swim 2.9 meters a second, or 9 feet, and 6 11/64 inches. (9.5144357 feet a second)
