Or at least, say what the rate is. If it’s 1%, compounded continually, then the investment will have doubled in about 69 years. So if it takes 6 x 50 = 300 minutes (and let’s say zero time on studying) Mark will have saved 600 minutes by the year 2081. Or is that saved 300 minutes, after accounting for the 300 minute investment? I’m not used to using exponentials for time savings...
