The velocity-time graph of an object moving along a straight line is shown in the figure. What is the distance covered by the object between \( t = 0 \) to \( t = 4s \)? 
The distance traversed by an object is equivalent to the area bounded by its velocity-time graph. The provided graph comprises both trapezoidal and rectangular sections. The total area delineated by the graph from \( t = 0 \) to \( t = 4 \) quantifies the distance traveled. The calculation of this area yields: \[ {Distance} = {Area under the graph} = 13 \, {m} \]
