What was the average speed of the cyclist during the first 5 hours of their journey?

The cyclist's journey is represented by graph 1. In the first 5 hours, the cyclist travels from 0 km to 50 km.

• Distance traveled = 50 km - 0 km = 50 km
• Time taken = 5 hours - 0 hours = 5 hours
• Average speed = Distance / Time = 50 km / 5 hours = 10 km/h

Ответ: 10 км/ч
