Average Speed Calculation for Truck Travel
This problem asks us to find the average speed of a truck based on its travel distance over two consecutive hours. The average speed is a measure of the total distance covered divided by the total time taken.
Given Information:
- Distance covered in the first hour: 75 km
- Distance covered in the second hour: 33 km
Steps to Calculate Average Speed:
To find the average speed, we need two main components: the total distance traveled and the total time elapsed.
-
Calculate Total Distance:
Add the distances covered in each hour.
Total Distance = Distance (1st hour) + Distance (2nd hour)
Total Distance = 75 km + 33 km = 108 km
-
Calculate Total Time:
Add the time duration for each part of the journey.
Total Time = Time (1st hour) + Time (2nd hour)
Total Time = 1 hour + 1 hour = 2 hours
-
Calculate Average Speed:
Use the formula for average speed:
Average Speed = $ \frac{\text{Total Distance}}{\text{Total Time}} $
Substitute the calculated values:
Average Speed = $ \frac{108 \text{ km}}{2 \text{ hours}} $
Average Speed = 54 km/h
Conclusion:
The average speed of the truck over the two hours is 54 km/h. This means that, on average, the truck covered 54 kilometers every hour during its journey.
