Sorry guys need help again
A particle moves through space at a speed of 210 metres per second for 5.2 x 10 to the power of 8 seconds
Calculate how far the particle will have travelled.
Give your answer in standard form, correct to 3 significant figures.
Working needed for 3 marks.

this is straight up multiplication ... what do you get?

As Skeeter pointed out, this is simply a multiplication question.
1 second = 210 metres
2 second = 210 x 2 metres
$\displaystyle 5.2 \times 10^8$ seconds = 210 x ($\displaystyle 5.2 \times 10^8$) metres
easy :)
