Rachel can make 16 cards in 5 minutes. How many cards can she make in 1 hour

Answer 1

Since 60 minutes is equivalent to 1 hour, we can multiply this rate by 12 to find out how many cards she can make in one hour (Recall that 12 times 5 is 60).

16 * 12 = 192 cards in one hour

Also there are 12 five- minute periods in one hour.
