Heeeey everybody :)
11. In everyday speech, in a jiffy means in a very short time. In science, a specific value sometimes assigned to a jiffy is 1/100 s.
Naima can type at 50 words/min. On average, how many jiffies does she take to type each word?
Now this is how you solve it.
Well there are 60 seconds in a minute.
So 60 goes over 50 (60/50) and then you divide by 1o to get 6/5 then you multiply that by 1/100.
Then you multiply both numbers by the reciprocal 100/1 to get 600/5.
Then you simplify to get 120/1.
Therefore Naima types 50 words per every 120 jiffies.
