Certainly! Let's solve this step by step:
1. Identify the speed of the car: The car is driving at a constant speed of 45 kilometers per hour (km/h).
2. Identify the time duration: The car is traveling for a total of 3 hours.
3. Compute the distance: To find the distance traveled, we use the formula:
[tex]\[
\text{Distance} = \text{Speed} \times \text{Time}
\][/tex]
4. Insert the given values into the formula:
[tex]\[
\text{Distance} = 45 \, \text{km/h} \times 3 \, \text{h}
\][/tex]
5. Multiply the speed by the time:
[tex]\[
\text{Distance} = 135 \, \text{km}
\][/tex]
Therefore, the car travels 135 kilometers.
