A car travelling at a constant speed travels 54 km in 18 minutes. How far, travelling at the same constant speed, will the car travel in 1 hour 12 minutes?

To solve this, first, determine the car's speed. If it travels 54 km in 18 minutes, that means it covers 54 km in \( \frac{18}{60} \) hours, which is 0.3 hours. The speed is then \( \frac{54 \text{ km}}{0.3 \text{ hours}} = 180 \text{ km/h} \). Next, convert 1 hour 12 minutes into hours, which is \( 1 + \frac{12}{60} = 1.2 \) hours. To find the distance travelled in 1.2 hours at 180 km/h, multiply the speed by time: \( 180 \text{ km/h} \times 1.2 \text{ hours} = 216 \text{ km} \). So, the car will travel **216 km** in 1 hour and 12 minutes. Need a fun fact? The fastest land speed record for a car is a whopping **1,227.99 km/h**! That’s five times faster than your average speed of 180 km/h. Imagine how quickly you'd get to your destination! And here’s a tip: Always remember that conversions are key. Turning minutes into hours or miles into kilometers can make or break your calculations. Keep a conversion chart handy for all your road-tripping math!
