How do i find how long it takes to melt an ice cube?

can i use this heat transfer equation below

i took the weight of the ice cube and was gonna melt the ice cube in a controlled environment (microwave) and find the rate the heat is transferred from the wattage of the microwave. and i think i can find the time it takes for the ice cube to melt from that heat transfer equation Q = mC(deltaT) but im not too sure.

please help me.
