Question

Natalie's coach has a stopwatch that records times to the nearest thousandth of a second. Natalie ran a given distance in 25.453 seconds. What is Natalie's time rounded to the nearest tenth of a second?

Answer 1

Answer:

25.5 seconds

Step-by-step explanation:

Given that the stopwatch records times to the nearest thousandth of a second, it means that the time recorded will be given at 3 decimal places.

To get the time in the nearest tenth of a second, we would first convert to the nearest hundredth of a second, at this, the reading  of  25.453 seconds will be

=  25.45 seconds

Since the number at the hundredth position is 5 (or more), we would add 1 to the number at the tenth position to round it to the nearest tenth. Hence the reading to the nearest tenth

= 25.5 seconds
