\(\mathrm{t}_{87.5}\) is the time required for the reaction to undergo \(87.5 \%\) completion and \(\mathrm{t}_{50}\) is the time required for the reaction to undergo \(50 \%\) completion. The relation between \(\mathrm{t}_{87.5}\) and \(\mathrm{t}_{50}\) for a first order reaction is \(\mathrm{t}_{87.5}=x \times \mathrm{t}_{50}\) The value of \(x\) is ___________. (Nearest integer)
