Answer
$\approx 1.6$ million miles
Work Step by Step
One full revolution $(2\pi$ rad) of the earth is a year,
so in one day,
the central angle traversed by the earth is
$\displaystyle \theta=\frac{1}{365}\cdot 2\pi$ rad
The length $s$ of an arc that subtends
a central angle of $\theta$ radians is $ s=r\theta$.
$ s=\displaystyle \frac{1}{365}\cdot 2\pi\cdot 93\approx$1.60092118786
$\approx 1.6$ million miles
