Answer:
The speed is 1.5 m/s.
Step-by-step explanation:
Given that,
Distance = 3 m
Time = 2 sec
We know that,
The position and time graph shows the speed of motion.
We need to calculate the speed
Using formula of speed

Where, d = distance
t = time
Put the value into the formula


Hence, The speed is 1.5 m/s.
