Question

A standard roll of toilet paper is 304 feet long. If Bob walks at a steady rate of five feet per second, how much time does it take him to walk the length of the roll. Convert your answer to minutes.

Answer 1

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:

$v=d/t$

The function can be expressed to make t the subject to calculate time taken by Bob;

$v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min$

Hence, it takes Bob 1.01 minutes to walk the length of the roll.
