<p>A body moves on a frictionless plane starting from rest. If&nbsp;<span class="equation">\(S_n\)</span>&nbsp;is distance moved between t = n - 1 and t = n and&nbsp;<span class="equation">\(S_{n-1}\)</span>&nbsp;is distance moved between t = n - 2 and t = n - 1, then the ratio&nbsp;<span class="equation">\(\frac{S_{n-1}}{S_{n}}\)</span>&nbsp;is (1 -&nbsp;<span class="equation">\(\frac{2}{x}\)</span>​​​​​​​) for n = 10. The value of x is_____</p>
