                    example 3. Ravi travelled 17 km 352 m on Monday and 14 km 65 m on Tuesday. Find
                    the total distance travelled by Ravi in these two days.
                    Solution.

                                                                  km      m

                    Distance travelled on Monday =                17    352
                    Distance travelled on Tuesday =            +  14     65

                    Total distance travelled               =      31     417

                    Thus, Ravi travelled 31 km 417 m in these two days.

                    example 4. A tree was 21 m 75 cm high. It broke from the top at a height of 12 m 24 cm,
                    due to a storm. How much of the tree is still standing upright?
                    Solution.

                                                                    m     cm
                    Height of tree before breaking =                21    75

                    Hight of broken part                    =   – 12      24
                    Height of upright tree                  =       9     51

                    Thus, 9 m 51 cm of the tree is still standing upright.

                                Exercise 9C

                        1.  Add the following:

                           a.       km m                   b.        m cm                  c.      cm mm
                                     23 175                         241 43                         43    4
                                  + 23 104                        +  28 91                       + 37    9

                       2.  Write in the vertical form and add the following.

                           a.  18 m 65 cm and 9 m 56 cm                    b.  63 m 64 cm and 15 m 69 cm

                       3.  Find the difference:

                           a.       km    m                b.        m cm                  c.      km    m

                                  – 18    357                     – 10    98                     – 46 187

                                                                                                                 155
