The distance traveled is #"6.1 mi"#.

The formula for speed is #s=d/t#, where #s="speed, d=distance, and t=time"# .

Known/Given
#s=3.5"mi/h"#
#t=1.75"h"#

Unknown
distance

Equation
#s=d/t#

Solution
Rearrange the equation to isolate distance, then solve for distance.

#s*t=d#

#(3.5"mi/h")(1.75"h")=d#

#"6.125 mi"=d#

Switch sides.

#d="6.125 mi"="6.1 mi"# rounded to two significant figures.
