quick physics problem regarding displacement.?

The velocity of a diver just before hitting the water is -10.1 m/s (motion is directly downward). What is her displacement during the last 1.20 seconds of the dive? i dont know where to start or what equation to use for this problem. thanks!

the formula

v = s/t where v = velocity, s = displacement, t = time in seconds.

assuming that the velocity is constant,

s = vt

s = -10.1 (1.2)

= 1.212 metres downwards.

Starting from the origin with Vi = 0, X = ½a*t² = ½*(-3)*5.0² = -37.5 m The answer can’t be anything with a + in front of it……
