Four times as many minutes ... compared to what? four times as many minutes as between three o'clock "now" (the time being asked for) .... sorry my working was a bit ambiguous, hope now it is clear.

I think he is saying that if it is x minutes past 3:00 right now, then 50 minutes ago it was 4x minutes past 3:00. Is this correct? Quote Link to comment Share on other sites More sharing options...

Is this correct? Well it would be less, not more, right? Why I asked. But the explanation provided an answer, above. Quote Link to comment Share on other sites More sharing options...
