Answer:
1.01 minutes
Step-by-step explanation:
The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.
Velocity is defined as the rate of change of displacement over time t:
![v=d/t\\](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C)
The function can be expressed to make t the subject to calculate time taken by Bob;
![v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C%5Ctherefore%20t%3Dd%2Fv%2C%20d%3D304%2C%20v%3D5%5C%5C%5C%5Ct%3D%5Cfrac%7B304%7D%7B5%7D%5Ctimes%20%5Cfrac%7B1%7D%7B60%7D%5C%20min%5C%5C%5C%5Ct%3D1.01%20%5C%20min)
Hence, it takes Bob 1.01 minutes to walk the length of the roll.
