Beyond the Answer

To determine Bill's velocity, we first need to convert the distance he walked into meters and the time he took into seconds. Bill walked 4.5 miles, which is approximately 7,242 meters (since 1 mile is approximately 1,609.34 meters). He took 87 minutes, which is equivalent to 5,220 seconds (since 1 minute is 60 seconds and \( 87 \times 60 = 5,220 \) seconds). Now, we can calculate Bill's velocity using the formula: \[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} = \frac{7,242 \, \text{meters}}{5,220 \, \text{seconds}} \approx 1.39 \, \text{m/s}. \] Therefore, Bill's velocity during the walk is approximately \( 1.39 \, \mathrm{m/s}. \)
