Unformatted text preview: equivalence statements: 1 km = 1000m 1 m = 1.094 yd 1760yd = 1 mi To make sure the process is clear, we will proceed step by step: Kilometers to Meters 1000m 10.0 km X 1 km: = 1.00 X 10 4 m Meters to Yards 1.094 yd 1.00 X 10 4 rn X = 1.094 X 10 4 yd 1m Note that we should have only three significant figures in the result. Since this is an in-termediate result, however, we will carry the extra digit. Remember, round off only the final result. Yards to Miles- =vt we round to the correct num-nificant figures after each step e correct significant figures for lation. However, since you use ~~Tnr and combine steps on it, you d only at the end. 1mi 1.094 X 10 4 yd X 1760 yd = 6.216 mi Note in this case that 1 mi equals exactly 1760 yd by designation. Thus 1760 is an exact number....
