A dolphin is swimming at a depth of –3.4 meters with respect to sea level when it begins diving deeper at a constant rate of –0.25 meter per second. In how many seconds will the dolphin reach a depth of 9.9 meters below sea level?

Respuesta :

Answer: 26 s

Step-by-step explanation:

Given

Dolphin is 3.4 meters below the sea level

It started moving at a rate of [tex]-0.25\ m/s[/tex]

Distance travel in the vertical direction by dolphin is

[tex]\Rightarrow 9.9-3.4=6.5\ m[/tex]

time taken is given by

[tex]\Rightarrow time(t)=\frac{\text{Distance}}{\text{Speed}}\\\\\Rightarrow t=\frac{6.5}{0.25}=26\ s[/tex]
