Science homework help please !?

Question

Okay there is a generator that can produce 20 kW of power from one tank of diesel if some one uses 102 kWh per day how long would this tank last?

sorry I dont get it either :(

Answer 1

is answer 5.10 hr

power=20kW     let time=x hr

work=102kWh

since power =work done/time

=>20Kw=102kWh/x

=>x=102/20 h

=>x=5.1 hr.(5 hr 10 min)

hope its right!
