Each number is half the previous number.
half (1 hour) = 30 minutesIt is 0.5 hours.
The number that 30 is ten less than is 40. Half that is 20. So the question becomes "what number is as much more than 10 is less than 20". This is gobbledygook, but if I rephrase to say "what number is as much more than 10 than 10 is less than 20", then since10 is less than 20 by 10, I guess 20.
30/60 or 1/2
