V}_{2}}/4{{l}_{2}}\], where \[{{l}_{2}}=x\] according to the GIVEN situation and \[{{v}_{1}}<{{v}_{2}}\] as during summer, temperature would be higher, then \[\frac{3{{v}_{2}}}{4{{l}_{2}}}=\frac{{{v}_{1}}}{4{{l}_{1}}}\] \[\Rightarrow {{l}_{2}}=3{{l}_{1}}\times \frac{{{v}_{2}}}{{{v}_{1}}}\] \[\Rightarrow x=54\times \](a QUANTITY greater than 1) So x>54.
