A body moving along a straight line with uniform acceleration 'a' it covers a distance \[{{S}_{1}}\] in the first t seconds and a distance \[{{S}_{2}}\] in the next t seconds, a is then given by:

A) \[\frac{{{S}_{1}}+{{S}_{2}}}{{{t}^{2}}}\]               

B) \[\frac{3{{S}_{1}}+{{S}_{2}}}{{{t}^{2}}}\]

C) \[\frac{{{S}_{2}}+{{S}_{1}}}{{{t}^{2}}}\]   

D) \[\frac{3{{S}_{1}}+{{S}_{2}}}{2t}\]
