Answer:
100
Explanation:
Jane packs a towel on the rack every 12 seconds, the first thing we need to find out is: how many towels will she pack on the rack in a minute?
60 ÷12 = 5 (i divided 60 by 12 becouse: there are 60 seconds in a minute and she packs a towel every 12 seconds)
Ok, so we now know that in 1 minute she would have packed 5 towels on the rack (1 minute = 5 towels); however our aim is to find out how many towels will she pack in 20 minutes so we will multiply the amount of towels she will pack in one minute (5) by 20.
20 × 5 = 100
