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

The video tutorial explains how to solve a problem involving distance, speed, and time. It begins by setting up a scenario where Rushka needs to travel from Fulbeck to Horton via Gamby. The tutorial guides viewers through calculating the time taken to reach Gamby and the speed required to reach Horton on time. Key concepts such as converting time units and using the distance-speed-time triangle are emphasized. The tutorial concludes with a recap of the problem-solving process and important considerations for unit consistency.

What is the total distance Rushka needs to travel from Fulbeck to Horton?

• 10 miles

• 28 miles

• 30 miles

• 18 miles

If Rushka leaves Fulbeck at 10:00 and travels at 40 mph, what time does she reach Gamby?
