What does 1 minute equal to?

One thing i'll never forget about my Captain is the infamous question in the title. Before ambush, my team was late by just one minute to assemble after setting up our tents & cooking our rationed food. When we stood before him, he didn't shout or yell at us for being late. He calmly asked us the infamous question in a low voice, to which we replied, 60 seconds. And he simply said, "Squad position down. 60 push ups." Imagine doing that right after eating! A single second can be a matter of life or death in the army, what more a minute.. A good lesson on punctuality, and discipline.
