Answer :

To determine the distance that a car will travel in 1 hour when it is moving at a speed of 15 meters per second, let's follow these steps:

1. Convert the time from hours to seconds:
- There are 60 minutes in an hour.
- There are 60 seconds in a minute.
- Therefore, there are [tex]\( 60 \text{ minutes/hour} \times 60 \text{ seconds/minute} = 3600 \text{ seconds/hour} \)[/tex].

2. Speed and time relationship:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]

3. Substitute the given values:
- Speed = 15 meters per second.
- Time = 3600 seconds (which is 1 hour).

4. Calculate the distance:
[tex]\[ \text{Distance} = 15 \, \text{m/s} \times 3600 \, \text{seconds} \][/tex]

5. Perform the multiplication:
[tex]\[ \text{Distance} = 54000 \, \text{meters} \][/tex]

Thus, the distance the car will travel in 1 hour is 54,000 meters.
