Suppose that a bicyclist is biking with a velocity function of v(t) = 2t - 1 ft/min starting at t = 0, how long does it take the bicyclist to go 30ft?

we know that v=ds/dt i.e the integral of velocity is displacement v dt =ds integrate v(t) from 0 to t and integrate ds from 0 to 30 integrating both side we get t^2-t=30 solving for t we get t=-5,6 pick t=6 and thats the ans
