Questions: Mid-Term Review A baby crawls at a constant speed of 0.150 m / s down a hallway that is 3.72 m long. How much time does it take for the baby to crawl down the hallway? t=[?] s time (s)

Solution Steps

We are given the following values:

• Speed of the baby, \( v = 0.150 \, \mathrm{m/s} \)
• Length of the hallway, \( d = 3.72 \, \mathrm{m} \)

The formula to calculate time when speed and distance are known is:

\[ t = \frac{d}{v} \]

where:

• \( t \) is the time,
• \( d \) is the distance,
• \( v \) is the speed.

Substitute the given values into the formula:

\[ t = \frac{3.72 \, \mathrm{m}}{0.150 \, \mathrm{m/s}} \]

Perform the division to find the time:

\[ t = 24.8 \, \mathrm{s} \]
