<h2>Answer:</h2>

Answers in the explanation

<h2>Explanation:</h2>

The term speed is used to denote distance traveled divided by time. This can be expressed in a mathematical language as follows:

$v=\frac{d}{t} \\ \\ \\ v:speed \\ \\ d:distance \\ \\ t:time$

The cart with Low fan speed:

$v=\frac{500}{7.4} \\ \\ v=67.5675cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=67.6cm/s}$

The cart with Medium fan speed:

$v=\frac{500}{6.4} \\ \\ v=78.125cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=78.1cm/s}$

The cart with High fan speed:

$v=\frac{500}{5.5} \\ \\ v=90.9090cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=90.9cm/s}$
