Answer:
16 km
Step-by-step explanation:
From Washington, as the question asks, will now be considered 0 aka the starting point.
So as of now, we know Washington from Oakdale is 6.2 km.
And from Stanford to Salem is 11.9 km, also Salem to Washington is 10.3 km. Hence the addition of 11.9 km and 10.3 km to figure out the whole distance between Stanford and Washington.
11.9 km + 10.3 km = 22.2 km
Now we subtract 22.2 km to 6.2 km for the product of 16 km.
