Answer 2

Let's calculate the given expressions step by step:

1. 129 km 814 m + 375 km 218 m:

To add these two values, we add the kilometers separately and then the meters separately.

Kilometers: 129 km + 375 km = 504 km

Meters: 814 m + 218 m = 1,032 m

Therefore, the sum is 504 km 1,032 m.

2. 183 km 20 m - 96 km 531 m:

To subtract these two values, we subtract the kilometers separately and then the meters separately.

Kilometers: 183 km - 96 km = 87 km

Meters: 20 m - 531 m (Since 20 m is smaller than 531 m, we need to borrow 1 km or 1,000 m from the kilometers.)

20 m + 1,000 m = 1,020 m

1 km - 531 m = 469 m

Therefore, the difference is 87 km 469 m.

3. 16 m 24 s 46 cm + 3 dm 6 cm:

First, let's convert all the units to the same base unit, which is centimeters.

16 m = 16,000 cm (1 meter = 100 centimeters)

24 s = 24 cm (1 second = 100 centimeters)

46 cm + 3 dm 6 cm = 46 cm + 3 * 10 cm + 6 cm = 46 cm + 30 cm + 6 cm = 82 cm

Now, we can add the values:

16,000 cm + 24 cm + 82 cm = 16,106 cm

Therefore, the sum is 16,106 cm, which is equal to 161.06 m.

4. 46 km 758 m - 28 km 99 m:

To subtract these two values, we subtract the kilometers separately and then the meters separately.

Kilometers: 46 km - 28 km = 18 km

Meters: 758 m - 99 m = 659 m

Therefore, the difference is 18 km 659 m.

Summary of the calculations:

1. 129 km 814 m + 375 km 218 m = 504 km 1,032 m
2. 183 km 20 m - 96 km 531 m = 87 km 469 m
3. 16 m 24 s 46 cm + 3 dm 6 cm = 161.06 m
4. 46 km 758 m - 28 km 99 m = 18 km 659 m
