Final answer:
Using the formula distance = speed x time, the cyclist who traveled at a speed of 16 km/h for 3 hours covered a distance of 48 kilometers.
Step-by-step explanation:
The question 'A cyclist travels for three hours at a speed of 16 km/h. How far did the cyclist travel in kilometres?' can be answered using the basic distance formula: distance = speed × time. To solve this, simply multiply the cyclist's speed (16 km/h) by the time spent traveling (3 hours).
So the calculation would be: 16 km/h × 3 h = 48 km.
Therefore, the cyclist traveled 48 kilometers.
