Sam walked

$2 \frac 1 5 * 1 \frac 3 4 = (11)/(5) * (7)/(4) = (77)/(20) \textrm{ miles}$

Lisa walked fewer miles, so we'll get a negative number for how many miles more Lisa walked.

$\textrm{Lisa } - \textrm{ Sam } = (11)/(5) - (77)/(20) = (44)/(20) - (77)/(20) = - (33)/(20) = - 1 (13)/(20)$

Answer: -1 13/20 miles
