Question

A teacher tells her students she is just over 1 and billion seconds old.

1. Write her age in seconds using scientific notation.

Answer 1

1,000,000,000 1 x 109
One year = (365)x(24)x(60)x(60)
Seconds = 31,536,000 seconds= 31.536 million seconds
So 1 Billion Seconds
(1000,000,000)/31,536,000= 31.536 years
So 1 billion seconds would be 31 years 8 mouths 19 days 1 hour 46 minutes and 4 seconds
