A CLYCLIST COVER 8 5/12 KM IN 3 HOUR HE COVERED 3 5/8 KM IN FIRST 2 HOUR .WHAT DISTANCE DID HE COVERED IN THIRD HOUR?

Answer 1

$$\begin{gathered} \mathrm{Distance}\mathrm{covered}\mathrm{in}3\mathrm{hours}=8\frac{5}{12}\mathrm{km}=\frac{101}{12}\mathrm{km} \\ \mathrm{Distance}\mathrm{covered}\mathrm{in}\mathrm{first}2\mathrm{hours}=3\frac{5}{8}\mathrm{km}=\frac{29}{8}\mathrm{km} \\ \mathrm{Distance}\mathrm{covered}\mathrm{in}\mathrm{third}\mathrm{hour}=\frac{101}{12}-\frac{29}{8} \\ =\frac{202-87}{24} \\ =\frac{115}{24} \\ =4\frac{19}{24}\mathrm{km} \end{gathered}$$
