Answer: To determine the average speed at which Sphenathi and the other matriculants must travel to reach Uptington by 09:45, we need to know the distance between Bloemfontein and Uptington.
Once we have the distance, we can use the formula:
Average Speed = Total Distance / Total Time
Given that we don't have the distance between Bloemfontein and Uptington, it's not possible to calculate the average speed accurately. If you can provide the distance, I can assist you further in calculating the average speed.
