Answer 3

To subtract the distances, we'll need to convert both distances to the same unit, either all in kilometers or all in meters. Let's convert them to meters for consistency:

8 km 23 m = (8 * 1000 m) + 23 m = 8,000 m + 23 m = 8,023 m 6 km 148 m = (6 * 1000 m) + 148 m = 6,000 m + 148 m = 6,148 m

Now we can subtract the distances: 8,023 m - 6,148 m = 1,875 m

Therefore, 8 km 23 m - 6 km 148 m is equal to 1,875 meters.

For the addition of the times, let's add the hours and minutes separately and then adjust the result if necessary:

6 hours 48 minutes + 19 hours 32 minutes: Hours: 6 + 19 = 25 hours Minutes: 48 + 32 = 80 minutes

Since there are 60 minutes in an hour, we can convert the extra 80 minutes to hours by dividing it by 60: 80 minutes ÷ 60 = 1 hour and 20 minutes

Adding the extra hour to the total hours: 25 hours + 1 hour = 26 hours

Adding the remaining 20 minutes to the total minutes: So, the final result is 26 hours and 20 minutes.

Therefore, 6 hours 48 minutes + 19 hours 32 minutes is equal to 26 hours 20 minutes.
