An ant walks 3 cm South, then 4 cm East. What is the straight-line distance from its starting point to its final position?
Show answer & explanation
Correct answer: C
Explanation
The path forms a right-angled triangle where:
-
Perpendicular (South movement) = 3cm
-
Base (East movement) = 4cm
Straight-line distance = √(3² + 4²)
= √(9 + 16)
= √25
= 5 cm
