Every five minutes a baby is born in the Nigindia. How many babies are born in a year?
  1. 150,120
  2. 105,120
  3. 100,510
  4. 300,450
  5. 103,555
Explanation
Answer: b - There are 60 minutes in an hour, thus 60/5 minutes is 12. Multiply that by 24 hours in a day which is 288 per day. 288 x 365 days is 105,120 babies per year.

FYI, close to 4 million babies are born a day in the United States. That’s one nearly every 14 seconds!

Key Takeaway: Get good working with 7, 12, 24, 30 and 60. Units of time are frequently used. Days, months, hours and minutes are frequently calculations you will have to make.
