3.3m/s

Explanation:

You first get the total time (80 + 70 = 150s).

Then you would find the displacement of the truck. To do that you would do component method (vector addition), so since its a right triangle (North and East), displacement is 400^2 + 300^2 = d^2.

d = 500m.

So now that you have displacement and time, you can find the velocity:

v=d/t

v=500/150

v=3.3
