I have the velocity of v(t)= -t +8 when t is greater than 6 and less than or equal to 11. I need to know the distance function f(t) that corresponds to the v(t).

I also have the velocity of v(t)= 3t-36 when t is greater than 11 and less than or equal to 12. I need to know the distance function f(t) that corresponds to the v(t).

Thanks.
