Please explain to me how to do this Physics problem please.?

The total charge that an automobile battery can supply without being recharged is given in terms of ampere-hours. A typical 12-V battery has a rating of 60 ampere-hours (60 A for 1 hr, 30 A for 2 hrs, and so on). Suppose that you forget to turn the headlights off in your parked automobile. If each of the two headlights draws 3 A, how long will it be before your battery is "dead"?

    10 hours.

    60 amp-hours/6 amps = 10 hours
