1turn = 360 half a turn is 180
360+180=540
3/5 miles = 0.6 miles
0.6/4= 0.15 miles
Nikki walked 0.15 miles or 3/20 miles.
Multiply the bottom of the fractions together (4*5=20) and the tops (3*1=3) to get 3/20.
I think its 102 inches
2x3.5*2 power=24.5
4(24.5+1)=102
2 1/2 * 3
5/2 * 3/1
= 15/2
15/2 - 11 3/8
15/2 - 91/8
91/8 - 60/8
= 31/8 = 7 7/8
answer=7 7/8
