How long will it take for the car battery to go totally flat

Reference no: EM13668896

A surveyor out late accidentally leaves the car lights on. Each of the two front lights is 40 W and each of the two rear lights is 6W. The lights are linked in parallel across a 12V DC car battery. An identical battery can draw 0.5 A for 80 hours. Assuming it was fresh, how long will it take for the car battery to go totally flat?
