Question

It takes 2 hours and 32 minutes to wash 4 loads of clothes in a washing machine. At the same rate

Answer 1

Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.

Answer 2

It’ll take 5 hours and 26 mins. Here’s how: Turn 2 hours 32 mins into minutes completely: 152 mins. Take that and divide it by the amount of loads (4) to get the number of minutes it takes for each load: 38 minutes. Multiple the mins it takes for each load (38) by 7 to get 266 minutes. Subtract by 60 (because dividing will give you a decimal) to group 266 into hours. You’ll get 5 pairs of 60 with a spare if 26 which means you’ve got 5 hours and 26 minutes.
