The doctor's car departed at noon from the doctor's dispensary in village N to city B for a meeting scheduled at 1:10 pm. Usually the doctor moved at the same speed and arrived in city B exactly one hour later. However, after time t after the start of the movement, when the doctor was moving next to the building under construction, the car ran over a nail and punctured the wheel. To replace the wheel, he spent a time equal to t/3. To arrive 10 minutes before the start of the meeting, the driver had to move the rest of the way at twice the speed planned. At what time did the driver puncture the wheel? ​
