The position of a particle moving along a coordinate is s=√45+6t, with s in meters and t in seconds. Find the rate of change at t=6 seconds?

s=√45+6t OR s=√(45+6t)

ds/st = 6t
when t=6. ds/dt=36.
rate of change at t=6 seconds is 36

OR

ds/st = 6t/√(45+6t)
when t=6. ds/dt=4
rate of change at t=6 seconds is 4
