Amar went to Rishikesh for rafting. He faced an accident and his boat got punctured, so he called for help. Hearing this, a lifesaver who can row 24 km/h in still water left the tent to rescue Amar and it took him 1 hour to row to the accident site and come back. If the river is running at 3.6 km/h, how far is the accident site from the tent.
