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

johnweldon1993 · Answer

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

anonymous · Answer

so the answer would be 8

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