Answer 2

To solve the given arithmetic expressions, let's break them down step by step:

1. 35km 820m - 7km 900m: To subtract these distances, we need to convert them to the same unit. Since 1km = 1000m, we can convert the kilometers to meters. 35km 820m = (35 * 1000) + 820 = 35,000 + 820 = 35,820m 7km 900m = (7 * 1000) + 900 = 7,000 + 900 = 7,900m

Now, we can subtract these distances: 35,820m - 7,900m = 27,920m

Therefore, the result is 27,920m.

2. 1h 26min + 2h 34min: To add these times, we add the hours separately and the minutes separately. 1h + 2h = 3h 26min + 34min = 60min (since 26 + 34 = 60)

So, the total is 3 hours and 60 minutes, which can be simplified to 4 hours.

Therefore, the result is 4 hours.

3. 2h 30min - 55min: To subtract these times, we subtract the hours separately and the minutes separately. 2h - 0h = 2h 30min - 55min = -25min (since 30 - 55 = -25)

Since we have a negative result for the minutes, we need to borrow 1 hour from the hours component. 2h - 1h = 1h 60min - 25min = 35min

Therefore, the result is 1 hour and 35 minutes.

4. 13t 250kg + 820kg: The "t" represents metric tons, and 1 ton equals 1,000 kilograms. So, we need to convert the tons to kilograms. 13t 250kg = (13 * 1000) + 250 = 13,000 + 250 = 13,250kg

Now, we can add these weights: 13,250kg + 820kg = 14,070kg

Therefore, the result is 14,070 kilograms.

To summarize:

1. 35km 820m - 7km 900m = 27,920m
2. 1h 26min + 2h 34min = 4 hours
3. 2h 30min - 55min = 1 hour 35 minutes
4. 13t 250kg + 820kg = 14,070 kilograms
