Answer 2

C) 85 km

Clearly, the line has cut till the 85 km w.r.t. the Y-axis. So the total distance becomes 85 km.

More:-

• If the graph is an inclined straight line in s-t graph, then it is in uniform motion. And if not so, then it is in non-uniform motion.
• The slope of

1. s-t graph shows speed of the particle.
2. v-t graph shows acceleration.

Slope = $\boxed{\sf{\bf{\frac{y_2 - y_1}{x_2 - x_1}}}}$

• If the graph of two or more particles meet at a single point, that means they met in there in case of s-t graph.
• If the graph of acceleration time graph is a straight line parallel to the time axis, then the v-t graph is an inclined straight line.
• The independent unit is placed in the X-axis and the dependent one in the Y-axis.
