Two tugboats pull a disabled super tanker. Each tug exerts a constant force of 1.20×106 \rm N, one at an angle 19.0^\circ west of north, and the other at an angle 19.0^\circ east of north, as they pull the tanker a distance 0.670 \rm km toward the north.

 

What is the total work done with the two tugboats on the super tanker?
