Question

Sally averaged that she spent about 6.8×10^4 seconds training for her weight lifting competition in the month of May. Write this time in standard notation.

Answer 1

t = 68000 s

Explanation:

Given that,

The average time Sally spent for training for her weight lifting competition in the month of May is
`6.8* 10^4\ s`.

We need to write this time in standard notation.

The power of 10 is 4. 10⁴ can be written as 10000.

`6.8* 10^4=(68)/(10)* 10000\\\\=68000`

So, the standard time is equal to 68000 s.
