b. 1920 m
Work Step by Step
a. Since the measurements 295 m, 91.3 m, 1920 m, and 0.360 m have three significant digits, then they have the same accuracy.
b. Since the precision of the measurements 1920 m is 10, then it is the least precise measurement. The other values have precisions of 1, 0.1 and 0.001.
