How long will my car drive after jump starting?

My car, ford focus 2004 1.6, has for 2 days now not turned on. When attempted to, it makes ticking sounds. Radio still works everything just not turning on. Themiles per hour stick keeps ticking too.
Push starting works but needs done everytime as it doesn't turn on again. How long will the car drive if jump started with leads?
2 weeks ago I had the same problem and jump started it and it lasted 2 weeks.
Taking it to garage on Saturday. But for now, will jump starting work and how long for?

Impossible to say without knowing why it is going flat. If the alternator is not charging or can't charge the battery at all as the battery is past redemption then it may last a few yards. Jump starting puts little or no charge into a car battery.
may have lasted 2 weeks a while ago but since the problem may have got worse meaning it will last a far shorter time

Jump starting just works to get the car home or to a repair shop. A dead battery rarely charges much just by driving the vehicle. You would need to go 100 miles with the rpms over 2,500 rpm to have any chance of the car starting again in cold weather. A mechanic needs to charge the battery 6 hours with a battery charger set to 12 volts.10 amps before being able to test it properly.

Tried to jump start and it works. As soon as I turn it of it ticks. Doesn't work again. Taking it to garage on Saturday to see. Will charge it tonight and see how it goes.
