If a car travels 1/100 of a kilometer each second, how many kilometers does it travel in one hour?

If a car travels 1/100 of a kilometer each second, how many kilometers does it travel in one hour?

• A. 36
• B. 60
• C. 72
• D. 100

Answer: (A)

To determine how many kilometers a car travels in one hour when it travels 1/100 of a kilometer each second, we first need to understand the conversion between seconds and hours. There are 60 seconds in a minute and 60 minutes in an hour, which makes a total of 3600 seconds in one hour (60 seconds/minute × 60 minutes/hour = 3600 seconds/hour). Given that the car travels 1/100 of a kilometer each second, we can calculate the total distance traveled in one hour by multiplying the distance per second by the total number of seconds in an hour: \[ \text{Distance in one hour} = \left(\frac{1}{100} \text{ kilometer/second}\right) \times 3600 \text{ seconds} \] Now, performing the multiplication: \[ \frac{1}{100} \times 3600 = \frac{3600}{100} = 36 \text{ kilometers} \] Thus, the car travels 36 kilometers in one hour. This makes the answer 36 kilometers, aligning perfectly with the choice denoted as A, confirming that this is the correct interpretation and calculation based on the provided rate of travel.

To determine how many kilometers a car travels in one hour when it travels 1/100 of a kilometer each second, we first need to understand the conversion between seconds and hours.

There are 60 seconds in a minute and 60 minutes in an hour, which makes a total of 3600 seconds in one hour (60 seconds/minute × 60 minutes/hour = 3600 seconds/hour).

Given that the car travels 1/100 of a kilometer each second, we can calculate the total distance traveled in one hour by multiplying the distance per second by the total number of seconds in an hour:

[

\text{Distance in one hour} = \left(\frac{1}{100} \text{ kilometer/second}\right) \times 3600 \text{ seconds}

]

Now, performing the multiplication:

[

\frac{1}{100} \times 3600 = \frac{3600}{100} = 36 \text{ kilometers}

]

Thus, the car travels 36 kilometers in one hour. This makes the answer 36 kilometers, aligning perfectly with the choice denoted as A, confirming that this is the correct interpretation and calculation based on the provided rate of travel.
