Answer:5.54 miles ( with the assumption both cyclist possess the same acceleration )
Explanation:
Let a= distance between the cyclists
b= distance travelled by state street cycler
c = distance travelled by main street cycler
From the question b=c
Using cosine rule
a^2= b^2+c^2- 2*b*c *cos(135°)
a^2= 30.72
a= sqrt(30.72)
a= 5.54miles
