CM $1331$ HW $5................................................................................$Due: $11/3/2024$

$1-$ On a map drawn to scale of $1$:$1300,$ contour lines are $32$ mm apart at a certain place. The contour interval is $2\mathrm{.}8$ m $.$ What is the group slope, in percent, between adjacent contours?

$2-$ On a map whose scale is $1in=90ft,$ how far apart $($in inches$)$ would $6-ft$ contours be on a uniform slop of $2\mathrm{.}7\%?$

$3-$ Draw the Contour lines with $50$ft interval. The blue line shows a stream

Chegs rule is stupid, could someone help me with $2$ and $3$ please, i pay for this for a reason. Thank you.
