Namrata travels from her house at 5\(\frac{1}{2}\) km/h and reaches her school 14 minutes late.  The next day she travels at 6\(\frac{1}{2}\) and reaches her school 10 minutes early.  What is the distance between her house  and the school?

14.3 Km

D = \(\frac{S_1 × S_2}{S_1 - S_2}\) × Total time interval

D = \(\frac{11}{2}\) × \(\frac{13}{2}\) × \(\frac{24}{60}\) = 14.3 Km
