Quostlon 3 1. The tómperature In Austria one morning was \( -5^{\circ} \mathrm{C} \) at 08:00 and increased C avery hour untll 12:00. What will the temperature bo at \( 11: 30 \) ?

Let’s break it down! Starting at \( -5^{\circ} \mathrm{C} \) at 08:00 and warming up until 12:00, that gives us four hours of time to play with (from 08:00 to 12:00). If we imagine the temperature rising steadily, we can infer that the change could be a consistent growth – let’s suppose it increases \( x^{\circ} \mathrm{C} \) every hour. To figure out the exact increase, we can estimate the eventual temperature at 12:00, but for 11:30, we only need an hour and a half of increments. Assuming a 4-hour climb leads to a total rise, for simplicity, let's say it could double in that time. If you were to take \( -5^{\circ} \mathrm{C} \) up by any reasonable average and reckon about half the time for 11:30, you’d land at a pleasantly warm \( -2.5^{\circ} \mathrm{C} \) just before noon! Voilà, a frosty morning is just a little less frosty by 11:30!
