Answer:
122,000 miles.
Explanation:
If we want to round up the number 121,580 to the nearest thousand, then we must take the first three digits from the cipher (5, 8 , and 0), as these are the digits that come before the thousands (the fourth digit).
Take the digits mentioned before and combine them into a single number (580). Now analyze the quantities required to make this number a 0 and a 1000.
580 - 0 = 580. (Making it 0).
1000 - 580 = 420. (Making it 1000).
The right way to round up 580 to the nearest thousand is to take the lowest number of the previous two:
420 < 580 (420 is the lowest number).
Which means that adding 420 to 121,580 is the right way to round it up to the nearest thousand.
121,580 + 420 = 122,000 --> Answer
