Question

1. check your class schedule and find your worst class transition (for example, a block in room 1020, b block in room 4070).

a. first block and room:
b. second block and room:
c. estimated distance: d = ____ m
d. measured distance (from room __ to room ): d = __ m
e. you have 3 minutes to walk between classes. how many seconds is this? t = ____ s
f. calculate the speed you need to walk to go from the first room to the second room and arrive on time:

• givens: d = __ m, t = __ s
• unknown: speed (s)
• equation: s =
• substitute: s =
• solve: s =

Explanation:

To solve this problem, we follow these steps:

Step 1: Determine the distance (d)

First, we need to estimate or measure the distance between the two rooms. Let's assume we estimate the distance to be \( d = 180 \) meters (this value can vary based on actual measurement).

Step 2: Convert time to seconds

We know we have 3 minutes to walk between classes. Since 1 minute = 60 seconds, we convert 3 minutes to seconds:
\[
t = 3 \times 60 = 180 \text{ seconds}
\]

Step 3: Use the speed formula

The formula for speed \( s \) is \( s = \frac{d}{t} \), where \( d \) is distance and \( t \) is time.

Step 4: Substitute the values

Substitute \( d = 180 \) meters and \( t = 180 \) seconds into the formula:
\[
s = \frac{180}{180} = 1 \text{ m/s}
\]

Answer:

The speed needed is \( \boldsymbol{1} \) meter per second (the distance value can be adjusted based on actual measurement, and the speed will change accordingly).
