Suppose the earth's polar ice caps melted, sending water towards the equator and increasing the moment of inertia of the earth to 1.1 times its present value.
what happens to the duration of the day?

This is a question about angular momentum, which is conserved, and which will therefore be equal before and after the melt-down.
Angular momentum is calculated as I*w where I is moment of inertia, and w is angular velocity. With subscripts 1 & 2 referring to before and after melt-down we can write I1*w1 = I2*w2
w2/w1 = I1/I2 = 1/1.1 = 0.909 ...
