Question

Two runners take part in a race.
The graph shows how the speed of each runner changes with time.

What does the graph show about the runners at time t ?

• A. Both runners are moving at the same speed.
• B. Runner 1 has zero acceleration.
• C. Runner 1 is overtaking runner 2.
• D. Runner 2 is slowing down.

Answer 1

The correct option is A Both runners are moving at the same speed.

Since at time 't' the graphs are intersecting the corresponding value of speed from the y-axis will be same for both. So, we can infer that the speed will be same at time 't'.
