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

c. 56 km 45 m and 16 km 75 m d. 18 km 26 m, 9 km 36 m and 39 km 77 m
