GCSE Secondary Maths Age 13-17 - Number: Upper and Lower Bounds - Explained

The video tutorial explains how to determine if a train's average speed could exceed 160 km/h using upper and lower bounds for distance and time. It covers calculating these bounds, determining maximum speed, and the impact of measurement assumptions. The tutorial concludes that the maximum speed is 153.49 km/h, thus not exceeding 160 km/h. It also discusses how changing the rounding of the track's measurement affects the speed calculation.
