If a speedcuber's times for four cubes were 6.3 seconds, 6.7 seconds, 6.5 seconds, and 6.9 seconds, what was their average time?

1. Break Down the Problem

To find the average time, we need to calculate the sum of all the times and then divide that sum by the number of times recorded.

2. Relevant Concepts

The average can be calculated using the formula:
$\text{Average} = \frac{\text{Sum of times}}{\text{Number of times}}$

3. Analysis and Detail

1. Sum of Times:

   • $6.3 + 6.7 + 6.5 + 6.9$

2. Calculating the Sum: $6.3 + 6.7 = 13.0$ $13.0 + 6.5 = 19.5$ $19.5 + 6.9 = 26.4$

3. Number of Times:

   • There are 4 recorded times.

4. Verify and Summarize

Now, we can calculate the average: $\text{Average} = \frac{26.4}{4} = 6.6$

Final Answer

The average time for the speedcuber is $6.6$ seconds.
