Q1. A rope is 12 m 25 cm long. Another rope is 8 m 75 cm long. What is the total length?
Solution:
Rope 1 = 12 m 25 cm
Rope 2 = 8 m 75 cm
Add them:
12 m 25 cm + 8 m 75 cm = 21 m
The total length is 21 metres.
Q2. A road is 3 km 250 m long and another road is 5 km 450 m long. Find their total length.
Solution:
First road = 3 km 250 m
Second road = 5 km 450 m
Add them:
3 km 250 m + 5 km 450 m = 8 km 700 m
The two roads together are 8 km 700 m long.
Q3. A pipe is 2 m 65 cm long. Another pipe is 4 m 85 cm long. What is their combined length?
Solution:
Pipe 1 = 2 m 65 cm
Pipe 2 = 4 m 85 cm
Add them:
2 m 65 cm + 4 m 85 cm = 7 m 50 cm
Together the pipes measure 7 metres 50 centimetres.
Q4. A ribbon is 12 m long. If 4 m 40 cm is cut, how much ribbon is left?
Solution:
Ribbon length = 12 m
Cut off = 4 m 40 cm
Subtract:
12 m – 4 m 40 cm = 7 m 60 cm
The ribbon left is 7 metres 60 centimetres.
Q5. A road is 9 km 500 m long. If 4 km 750 m is built, how much is still left?
Solution:
Total road = 9 km 500 m
Built = 4 km 750 m
Subtract:
9 km 500 m – 4 km 750 m = 4 km 750 m
Still 4 km 750 m is left to be built.
Q6. A cloth is 8 m 60 cm long. 5 m 25 cm is used. How much is left?
Solution:
Cloth length = 8 m 60 cm
Used = 5 m 25 cm
Subtract:
8 m 60 cm – 5 m 25 cm = 3 m 35 cm
The cloth left is 3 metres 35 centimetres.
Solution:
Every day = 2 km
In 15 days = 2 × 15 = 30 km
The boy walks 30 km in 15 days.
Q8. A bus travels 125 km in 1 hour. How much distance will it cover in 6 hours?
Solution:
In 1 hour = 125 km
In 6 hours = 125 × 6 = 750 km
The bus will travel 750 km in 6 hours.
Q9. A park is 400 m round. A girl runs 8 rounds. How far does she run?
Solution:
One round = 400 m
8 rounds = 400 × 8 = 3200 m
3200 m = 3 km 200 m
The girl runs 3 km 200 m in 8 rounds.
Solution:
Total ribbon = 84 m
Number of parts = 12
Length of each = 84 ÷ 12 = 7 m
Each part is 7 metres long.
Q11. A road is 480 m long. It is divided into 6 equal sections. What is the length of each section?
Solution:
Road length = 480 m
Sections = 6
Each section = 480 ÷ 6 = 80 m
Each section is 80 metres long.
Q12. A man walks 45 km in 9 days. How many kilometers does he walk each day?
Solution:
Total distance = 45 km
Days = 9
Each day = 45 ÷ 9 = 5 km
The man walks 5 km every day.
