A distance-time graph indicates than an object moves 100 m in 4 s and then remains at rest for 6 s. What is the average speed of the object?

avg speed = d/time = 100 m/10 sec = 10 m/s

To find the average speed of the object, we need to divide the total distance traveled by the total time taken.

In this scenario, the object moves 100 m in 4 s and remains at rest for 6 s. Therefore, the total distance traveled is 100 m and the total time taken is 4 s + 6 s = 10 s.

To calculate the average speed, we divide the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 100 m / 10 s

Calculating this, we get:

Average Speed = 10 m/s

Therefore, the average speed of the object is 10 m/s.
