Calculating Average Speed
To calculate the average speed of the truck during the journey, we need to find the total distance traveled and the total time taken. The average speed is then calculated by dividing the total distance by the total time.
Step 1: Calculate the total distance
The truck travels 150 km in the first part of the journey and another 100 km in the second part. Therefore, the total distance traveled is 150 km + 100 km = 250 km.
Step 2: Calculate the total time
To calculate the total time, we need to find the time taken for each part of the journey and then add them together.
Time taken in the first part:
The truck travels 150 km with a speed of 50 km/h. To find the time taken, we can use the formula: time = distance / speed.
In this case, the time taken in the first part is 150 km / 50 km/h = 3 hours.
Time taken in the second part:
The truck travels 100 km with a speed of 25 km/h. Again, using the formula: time = distance / speed.
The time taken in the second part is 100 km / 25 km/h = 4 hours.
Total time taken:
Adding the time taken in the first and second parts, we get a total time of 3 hours + 4 hours = 7 hours.
Step 3: Calculate the average speed
Now that we have the total distance (250 km) and the total time (7 hours), we can calculate the average speed using the formula: average speed = total distance / total time.
In this case, the average speed of the truck during the journey is 250 km / 7 hours ≈ 35.71 km/h.
Conclusion
Therefore, the average speed of the truck during the journey is approximately 35.71 km/h. This average speed represents the overall rate at which the truck covered the total distance of 250 km in a total time of 7 hours. It is important to note that the average speed is not the same as the constant speed maintained by the truck throughout the journey, as the truck traveled at different speeds during different parts of the journey.
To calculate the average speed of the truck during the journey, we need to find the total distance traveled and the total time taken. The average speed is then calculated by dividing the total distance by the total time.
Step 1: Calculate the total distance
The truck travels 150 km in the first part of the journey and another 100 km in the second part. Therefore, the total distance traveled is 150 km + 100 km = 250 km.

The time taken in the second part is 100 km / 25 km/h = 4 hours.

A truck travels 150 km with a speed of 50 km/h and after that another ...
Speed=distance/time
distance= 250km
time first section= 150/50= 3 h (distance/ speed)
time second section= 100/25= 4 h
total time = 7 h
speed= 250/7=35.71 km/h
distance= 250km
time first section= 150/50= 3 h (distance/ speed)
time second section= 100/25= 4 h
total time = 7 h
speed= 250/7=35.71 km/h
