Determine the displacement of this particle from t=1s to t=3s

r=-(5,0m/s)t i + (10,0m/s^2)t^2 j + (7,0m -(2,0m/s^3)t^3) k

2. Relevant equations

3. The attempt at a solution

I dont have an idea how to do this if I should to it by replacing t by 1 and then getting the magnitude of the vector for example. or should i get the value of t = 1 by each component alone and substract the components of 3 - the components of 1 ?

I must finish this soon thanks for the help in advance
