Given data
*Alec is rising towards the surface of the water is u = 6.0 m/min
*The given distance is d = 8.4 m
The formula for the time taken by the Alec to rise is given as
[tex]t=\frac{d}{u}[/tex]Substitute the values in the above expression as
[tex]\begin{gathered} t=\frac{8.4}{6.0} \\ =1.4\text{ minute} \end{gathered}[/tex]Hence, the time is taken by Alec to rise is t = 1.4 minutes
