Particle with variable velocity

[fazal]

Homework Statement

A particle is moving along a straight trajectory. The distance covered by a particle is described by the function S(t)=2t^3+5t^2 , where t>0 is the time.

What is the distance covered by the particle by the time t=4

Homework Equations

The Attempt at a Solution

sub t=4 into the equation we get 2(4)^3+5(4)^2
=208 plse check fi this is correct??
