Find the distance traveled in 15 seconds by an object moving with a velocity of v(t)=20+7cos(t) feet per second.

We are given with the equation v(t)=20+7cos(t)  where v is the velocity with units feet per second and t is time in seconds. Velocity is the distance travelled by a moving object per unit time. in this case, we get first the velocity at t =15 equal to 26.76 feet per second. Distance is vt or equal to 410.42 feet.
