Hint...if it covers 1.6m in (1/2) seconds...then in 10 seconds at the same speed it will cover (x) It's a proportion $\large \frac{1.6m}{0.5s} = \frac{x}{10s}$ and solve for 'x'

@johnweldon1993 so the answer would be 16

5. johnweldon1993

Not quite...when we cross multiply we get [$\large 10\times 1.6 = 0.5x$ $\large 16 = 0.5x$ What would 'x' be?

so the answer would be 8

Not right again :/ $\large 16 = 0.5x$ ^ "One half of SOME number = 16*

Oh 32
