Answer:210 minutes or 3.5 hours
Step-by-step explanation:
As he is running at a speed of 8km/hr, he will cover 3km in 22.5 minutes.
So 12 km=22.5×(12/3)=90 minutes
Then he takes rest of half an hour after every 3km, so he takes 2 hours or 120 minutes of rest (12km/3km×half an hour).
Then total timing is (120 +90) minutes=210 minutes or 3.5 hours.
