Question

If a computer can do a calculation in 0.0000004 second how long in seconds would it take the computer to do 6,000,000,000,000 calculations. Write your answer in scientific notation?

Answer 1

Time taken for a caluculation `-> 0.0000004 " seconds"`
`color(white)(Time taken for a caluculatp` `-> 4 xx 10^-7" seconds"`

Time taken for 6,000,000,000,000 caluculations `-> 0.0000004 " seconds" xx 6,000,000,000,000`
`-> 4 xx 10^-7" seconds" xx 6 xx 10^12`

`=> 24 xx 10^5" seconds"`
