Answer:
t = 6.09 seconds
Explanation:
Given that,
Speed, v = 44.1 cm/s
Distance, d = 269 cm
We need to find the time interval of the marble. Speed is distance per unit time.
![v=\dfrac{d}{t}\\\\\implies t=\dfrac{d}{v}\\\\t=\dfrac{269\ \text{cm}}{44.1\ \text{cm/s}}\\\\t=6.09\ s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5C%5Cimplies%20t%3D%5Cdfrac%7Bd%7D%7Bv%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B269%5C%20%5Ctext%7Bcm%7D%7D%7B44.1%5C%20%5Ctext%7Bcm%2Fs%7D%7D%5C%5C%5C%5Ct%3D6.09%5C%20s)
Hence, the time interval of the marble is 6.09 seconds.
