Worked Solution
Step 1: Find each leg's time.
Leg 1 = 58 seconds
Leg 2 = 58 + 12 = 70 seconds
Leg 3 = 58 seconds (same as Leg 1)
Leg 4 = 70 ÷ 2 = 35 seconds (half of Leg 2)
Step 2: Add all four legs.
Total = 58 + 70 + 58 + 35 = 221 seconds
Answer: The relay takes 221 seconds.
Correct answer: 221 seconds
