Answer:
R = 5
Explanation:
The resultant displacement of the cyclist is R = 5.
The given data states that the cyclist travel 4 km and then travels 3 km. These form a vector when represented graphically and are perpendicular to each other. Therefore the resultant displacement is calculated using vector addition rule.
The given vectors are AB and BC, where PQ = 4 and QA = 3. Thereby, we have resultant displacement . see image.
