Hi,
Ans-
Let the radius of circle be r
radius of circle = r
circumference of circle=2*22/7*r
circumference of circle=44r/7
Car travels=1/4 of circle
distance traveled by Car travels=1/4*44r/7
distance traveled by Car travels=11r/7
displacement of car=r√2
ratio=11r/7 : r√2
There was your answer and please view the attached explanation file that I have created on my own using paint.exe software.
