Explanation:

Step1: Recall speed-distance formula

The core formula relating distance ($d$), speed ($s$), and time ($t$) is $d = s \times t$.

Step2: Substitute given values

Here, distance $d=256$ miles, speed $s=70$ mph. Substitute into the formula:
$256 = 70t$

Step3: Match to options

Compare the derived equation with the provided choices.

Answer:

256 = 70t
