Answer:
x = 6
y = 13
Step-by-step explanation:
since DE and JK are congruent, they are both 18
to find 'y':
3y - 21 = 18
3y = 39
y = 13
DF and JL are diagonals that are congruent so:
9x - 23 = 7x - 11
2x = 12
x = 6
2 miles = 3520 yards (Americans wtf)
200 yards for 1 group = 5 minutes
400 yards for 2 groups = 5 minutes
1 minutes for 2 group = 80 yards
3520 yards for 2 groups = (3520:80 or 3520:400*5) minutes
So the answer is 44 minutes.
