&gt; 3km   Total time to cover 3 km= 45 minutes + 15 minutes = 60 minutes = 1 hour   Thus 3 km is covered in 1 hour   Required distance to be covered = 12 km   Beginning from origin point, he covers 9 km in 3 hours taking 15 minutes rest after every 45 minutes. To complete 12 kms he goes another 3 km in 45 minutes.   Thus, total time he takes is 3 hours 45 minutes.   ANSWER: 3 hours 45 minutes
