Answer 2

Least precise recorded time is 48.9 seconds.

Step-by-step explanation:

Here, we need to write the recorded time that is least precise. The given options are (a) 48.9107 s (b) 48.91 s (c) 48.910 s (d) 48.9 s. The precision in any measurement is defined as closeness in any measurement.

First option is most precise as it is precised to four decimal places. Second option is precised to two decimal places. Third option is precised to 3 decimal places. But in option fourth, the recorded time is precised to one decimal place.

Hence, the correct option is (d).
