# Math Help - speed distance time

1. ## speed distance time

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.

Working needed for 3 marks.

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

3. As Skeeter pointed out, this is simply a multiplication question.

1 second = 210 metres
2 second = 210 x 2 metres

$5.2 \times 10^8$ seconds = 210 x ( $5.2 \times 10^8$) metres
