what is the greatest possible error of 350mi
Assuming that the measurement is to the nearest 0.01, the greatest possible error is 0.005.
If the numbers are rounded to the nearest 750, then 375 is the greatest possible error. Although you are not likely to have counted in 750s, it is quite possible that you counted in 50s (greatest error = 25). Or in tens (GE = 5) or in units (ones), when the greatest error is 0.5. The greatest possible error is half of the smallest unit of measurement.
