we have that
1/40 mi
Convert to ft
1 mi=5,280 ft
so
1/40 mi=(1/40)*5,280=132 ft
therefore
1/40 mi---------> greater than 94 ft
30 yd
Convert to ft
1 yd =3 ft
30 yd=30*3=90 ft
30 yd -------> less than 94 ft
1/20 mi
Convert to ft
1 mi=5,280 ft
so
1/20 mi=(1/20)*5,280=264 ft
1/20 mi --------> greater than 94 ft
1,128 in
1 ft=12 in
1,128 in=1,128/12=94 ft
1,128 in --------> equal to 94 ft
102 3/5 ft
102 3/5 ft =102+3/5=102.6 ft
102 3/5 ft -------> greater than 94 ft
Part B
the length in yards
1 yd =3 ft
so
94 ft=94/3=31.33 yd=31 1/3 yd
