Evaporation from a swimming pool

[jabbie3]

Homework Statement

A) How much energy is required to evaporate all the water in a swimming pool of area 119 m2 and depth 2.4 m on a typical summer day? (Please note that the temperature of the water in the lake stays the same.) (For latent heat of vaporization use 2200 kJ/kg.)

B) The intensity of sunlight is about 1038 W/m2. If all the energy is absorbed by the water in the pool, how long will it take the water to evaporate?

Homework Equations

I got part A which is 628320000000 J. That is correct. It's part B that I can't solve.

I know I use I=Q/t and solve for t.

The Attempt at a Solution

When i solve for t I get 605317919.1 s.

Im pretty sure it is in seconds so I convert it to days and i get 7005.99 days.

THIS ISNT CORRECT! IDK what I am doing wrong..any guidance or input will be greatly appreciated.

THANKS!

This is incorrect because it is the equation for electrical current. You are given the intensity I = 1038 W/(m^2). Look at the units. What terms are associated with "W" and "m^2"?
