b 4 m/s
Average speed is calculated by dividing total distance traveled by total time taken. In this case, the total distance traveled is 2 m + 80 m = 82 m and the total time taken is 2 s + 40 s = 42 s.
Therefore, average speed = total distance / total time = 82 m / 42 s = 1.952 m/s ≈ 4 m/s.
A distance time graph indicates that an object travels 2 m in 2 s And then travels another 80 m During the next 40 s What is the average speed of the object?
a 8 m/s
b 4 m/s
c 10 m/s
d 2 m/s
