Average speed= (Total Distance)/(Total time)
= (20 m + 40 m)/(5 sec + 5 sec)
=60 m/10 sec
=6m/s

As average speed is total time by total distance travelled so here total time = 20+40=60m and total distance =5+5=10sec so now 60/10=6m/s

Understanding Average Speed
Average speed is defined as the total distance traveled divided by the total time taken. To calculate the average speed of the object in this scenario, we will follow these steps:
Total Distance Traveled
- The object first travels **20 m** in **5 seconds**.
- It then covers another **40 m** in **5 seconds**.
Total Distance Calculation
- Total distance = 20 m + 40 m = **60 m**
Total Time Taken
- Time for the first part = **5 seconds**
- Time for the second part = **5 seconds**
Total Time Calculation
- Total time = 5 s + 5 s = **10 seconds**
Average Speed Formula
To find the average speed, we use the formula:
- Average Speed = Total Distance / Total Time
Substituting the Values
- Average Speed = 60 m / 10 s = **6 m/s**
Conclusion
The average speed of the object is **6 m/s**, thus the correct answer is option **'A'**. This shows that the object maintained a consistent pace over the total distance and time.
