Question

Which equation describes the fastest runner?

Answer 1

The equation distance $\bold{=2 \times \text { time }}$ describes the fastest runner.

Answer: Option D

Explanation:

The fastest runner is determined by how quick a person can reach the destination (i.e) in a less amount of time compared to others. Consider it took 10 seconds to the reach the destination x. Substitute time = 10 seconds,  

$0.5 \times 10=5$

$0.33 \times 10=3.3$

$0 \times 10=0$

$2 \times 10=20$

From the four options, the highest distance travelled for constant time is distance $\bold{=2 \times \text {time}}$.
