w=1.4

Step-by-step explanation:

11w+5w-1=65w-36

16w-1=65w-36

16w-65w= -36+1

-49w= -35

w= -35/-49

w= 1.4

We have to calculate how much can they run in one minute.
Sanja:
4 miles28 minutes
x  1 minute

x=(4 miles * 1 minute) / 28 minutes=1/7 miles

Arien:
8 miles72 minutes
x  1 minutes

x=(8 miles * 1 minute) / 72 minutes=1/9 miles.

so; 1/7 miles >1/9 miles

Therefore: Sanja will finish first.
