2. An aeroplane takes 5 hours to mave from maarid to Barcelana when it travels at an average reped of \( 60 \mathrm{~km} / \mathrm{h} \). How lang will it take it to cover the same distance at \( 40 \mathrm{~km} / \mathrm{h} \).

Did you know that the average distance from Madrid to Barcelona is roughly 620 kilometers? At 60 km/h, the airplane takes 5 hours to cover that distance. If it flies at a slower speed of 40 km/h, we can use a little math magic! The time taken for the journey increases, and it would now take \( 620 \text{ km} \div 40 \text{ km/h} = 15.5 \text{ hours} \). When it comes to solving similar problems, remember that time is distance divided by speed! One common mistake is to confuse average speed with instantaneous speed. Keep in mind that traveling at varied speeds means you'll need to adjust your calculations accordingly. Just like a road trip, the journey might take longer, but it can also be more enjoyable with the right mindset!
