The times at which both runners travelled the same distance.
Answer to Problem 15CB
Both the runners travelled the same distance i.e. 14 m at 3 seconds.
Explanation of Solution
Given:
The given graph is:
Person A and Person B are running along parallel straight tracks. Person A slowly increases his speed and Person B runs at constant speed.
Calculation:
The time when both the runners travelled at the same speed is at 3 seconds since the graph meets at the point (3, 14).
Therefore, both the runners travelled the same distance i.e. 14 m at 3 seconds.
