Question

position vs. time
which object moves at a faster speed?
the object represented by line a (red).
the object represented by line b (blue).
both objects have the same speed.

Explanation:

Step1: Calculate speed of Line A

Speed = $\frac{\text{Position}}{\text{Time}} = \frac{1\ \text{m}}{10\ \text{s}} = 0.1\ \text{m/s}$

Step2: Calculate speed of Line B

Speed = $\frac{\text{Position}}{\text{Time}} = \frac{8\ \text{m}}{10\ \text{s}} = 0.8\ \text{m/s}$

Step3: Compare the two speeds

$0.8\ \text{m/s} > 0.1\ \text{m/s}$, so Line B is faster.

Answer:

The object represented by line B (blue).
