Energy calculation with no time given

[mbm]

Homework Statement

suppose you had to carry ten 30lb concrete blocks up a 24ft ladder, to build a chimney. if you were paid for the work that you did on the blocks at the same price as electrical energy costs (14 cent kWh). how much money would you make from this job.

Homework Equations

energy = power x time

The Attempt at a Solution

should it be assumed that the whole time is an hour? or is there a way to calculate time

hmmm... How do I put this politely. Your relevant equation, isn't relevant to this problem. You could take a week to carry the bricks up the ladder and the energy would be the same as if it took you an hour.

Are you familiar with the kinetic and potential energy equations? They might be more useful here.
