To find out how far Usain Bolt could run in 10 seconds at an average speed of 10.4 meters per second, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Plugging in the values:
\[ \text{Distance} = 10.4 , \text{meters/second} \times 10 , \text{seconds} = 104 , \text{meters} \]
So, Usain Bolt could run 104 meters in 10 seconds.
