Total periphery = 2 pie r = 2x22/7x1 = 6.38 miles

avg rate = 3 miles / hr

it would take more than 2 hrs for johanna to complete the circle

Answer is c - 2<t<2.5

Hi

Answer is C

Catch point " Walked Once" ....

So the length is = 2 pi r = 6.28 miles
time=distance/speed 6.28/3=2.09

t > 2 but t<2.5


Cheers

I did not convert pi to 3.14, which is why I got the wrong answer. Thank you all.
