A Question of Distance
It was a beautiful sunny morning. The air was fresh and a mild wind was blowing against my windscreen. I was driving from Bangalore to Brindavan Gardens. It took me 1 hour and 30 minutes to complete the journey. After lunch I returned to Bangalore. I drove for 90 minutes. How do you explain it?
There is nothing to explain here. The driving time there and back is absolutely the same 90 minutes and 1 hour and 30 minutes are one and the same thing. This problem is meant for inattentive readers who may think that there is some difference between 90 minutes and 1 hour 30 minutes.
