Ok, so the total distance will be 4 kilometers
remember, distance=speed times time
the polar bear's distance=9km/h times t or 9t
t is time in hours
the floe's distance =3km/hr times t or 3t
total disatace=polar bear disatnce+floe's distance=9t+3t=12t
so when will this distance eqal 4km?
4=12t
divide both sides by 12
4/12=t
1/3=t
about 20 mins or 1/3 hour

Answer: x=50
Explanation:-
Exterior angles of all polygons add up to 360 degrees.
So, x+20+x+40+2x+2x=360
x+x+2x+2x+20+40=360
6x+60=360
6x=360-60
.:6x=300
x=300/6
x=50
