for covering 50 miles at the rate of 10 mph Hamxa needs 50/10= 5 hr now, from beginning After the first 0-10 miles he takes 6 minutes for rest then covering 10-20 miles he takes 6 another minutes for rest similarly after 20-30 miles he takes another 6, so does after 30-40 miles. Be careful , after 40-50 miles he needs not to take any rest as he has already completed the distance. so the total time will be 300 + (6+6+6+6)= 324
