How much time does it take to change your displacement by 25.0m east?

As you walk to class with a constant speed of 1.65 m/s , you are moving in a direction that is 16.2° north of east.

How much time does it take to change your displacement by 25.0 m east?

I know that v0 = 1.65 m/s. Would I use the equation: x = (v0 cosθ)t?


Any help or advice would be much appreciated.

Maybe you meant to say vx = (v0 cosθ)t

Yes. Would that be correct equation to use?

Yes, to get the velocity in the x (eastward) direction. Using this result, you can easily determine t.
