V = d / t => t = d / V

V ≥ r ; d = 350 => t = d / V ≤ 350 / r

Then, t ≤ 350 / r, which is option C.

brilliants [131]

Answer:

Step-by-step explanation:

One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
