GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Speed, Distance, Time - Explained

The video tutorial discusses a scenario where Axel and Leuthner are driving on a motorway and see a road sign indicating the distance and average time to Junction 8. Leuthner claims they need to exceed the speed limit to cover 30 miles in 26 minutes. The tutorial explains how to calculate the required speed using the distance-speed-time formula, converting minutes to hours for accurate mph calculation. The calculated speed is 69.23 mph, which is below the 70 mph speed limit, proving Leuthner's claim incorrect. The tutorial emphasizes the importance of unit conversion and provides a marking scheme for the calculation steps.
