Best answer
Correct Answer - Option 4 : 180 km

Given

Speed of the person = 20 m/sec

Formula used:

1 m/sec = (18/5) km/hr

Calculation:

Speed of the person = 20 m/sec

⇒ 20 × (18/5)

⇒ 72 km/hr

According to the question,

Total distance covered in given time = 72 × {2 + (1/2)}

⇒ 72 × (5/2)

⇒ 36 × 5

⇒ 180 km

∴ Total distance covered by the person in 2 hour and 30 minutes is 180 km.
