Janiya found that her playlist will play for 3.8×102 seconds, 6.3¯¯¯ ×105 minutes, 1.05¯¯¯¯¯ ×104 hours, or 4.39814¯¯¯¯¯¯¯¯¯¯¯¯ ×102 days. Which answer uses the most appropriate units?
The most appropriate units for this scenario would be days, since it is the largest unit of time.
To determine which answer uses the most appropriate units, we need to compare the values given in different units.
First, let's compare the seconds and minutes. We can convert the seconds to minutes by dividing the given value by 60:
3.8 × 10^2 seconds ÷ 60 = 6.3333 × 10^0 minutes
Comparing this to the value given in minutes:
6.3 × 10^5 minutes
We can see that the value in minutes is much larger than the converted value in minutes. Therefore, using minutes as the unit would be the most appropriate choice.
So, the answer that uses the most appropriate units is "6.3 × 10^5 minutes".
To determine which answer uses the most appropriate units, we need to compare the values given for each unit of time.
- 3.8×10^2 seconds
- 6.3×10^5 minutes
- 1.05×10^4 hours
- 4.39814×10^2 days
Since the value for minutes is the highest (6.3×10^5), it can be considered the most appropriate unit for expressing the duration of Janiya's playlist.
