After 2 hours and 15 minutes, I reached office. That’s 15 km in 135 minutes. In a more simplified terms, our shuttle has to travel at a speed of 6.6 kmph to cover that distance. To give more perception – I used to do brisk walking in treadmill as part of physio at 6.5 kmph. Technically speaking, I could just walk at a normal pace and still would have reached before my shuttle.
