Question

Determine the speed of ocean currents (m/s) moving water near Africa at 30 W passing Puerto Rico (70W) in one year.

Answer 1

The speed of ocean currents approximately is 0.4667 m/s

Solution:

As per the question:

The ocean currents water moves at 30 W near Africa and 70 W near Puerto Rico

Time taken, t = 1 year =
`365* 24* 3600 = 3.15* 10^(7) s`

The distance between Puerto Rico and Africa, x =
`1.46* 10^(7) m`

Thus

The speed of the ocean currents there:

speed,
`v = (d)/(t) = (1.47* 10^(7))/(3.15* 10^(7))`

`s = 0.4667 m/s`
