Answer 3

To solve this mathematical expression, you can add and subtract the given distances:

12 km 25 m - 9 km 308 m + 25 km 900 m

First, add the distances with the same units (kilometers and meters):

(12 km + 25 km) + (-9 km) + (25 km) + (25 m - 308 m + 900 m)

Combine the kilometers:

37 km + (-9 km) + 25 m - 308 m + 900 m

Now, add the kilometers separately from the meters:

(37 km - 9 km) + (25 m - 308 m + 900 m)

Subtract the kilometers:

28 km + (25 m - 308 m + 900 m)

Now, combine the meters:

28 km + (25 m - 308 m + 900 m)

25 m - 308 m + 900 m = 25 m - 308 m + 900 m = -283 m + 900 m = 617 m

So, the final answer is:

28 km + 617 meters

To convert this to a single unit, you can convert the meters to kilometers (since 1 kilometer = 1000 meters):

28 km + 617 m / 1000 km = 28 km + 0.617 km = 28.617 km

So, the result is approximately 28.617 kilometers.
