The time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.
<h3>Time of motion of the star fish</h3>
The time taken for the star fish to travel the given distance is calculated as follows;
s = ut + ¹/₂at²
55 = 11.8t + (0.5)(6.39)t²
55 = 11.8t + 3.195t²
3.195t² + 11.8t - 55 = 0
<em>solve the quadratic equation using formula method,</em>
where;
a = 3.195, b = 11.8, c = -55
t = 2.7 s
Thus, the time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.
