According to the problem the the moon has created an angle of θ= 1 degree 55min
Now we need to convert it into radian
therefore,
115/60 degree = 23/12 x π/180 rad
Let r be the radius of the earth
therefore, r = 6.4 × 106m
From I = rθ,
r = 1/θ
= 6.4 × 106 x 12 × 180/23 × π m = 1.91 × 108 m
Hence the answer is 1.91 × 108 m
