Answer:
147.3047 miles
Step-by-step explanation:
We know that
the length of arc= radius (r)× angle subtended at the center(θ in radian)
radius of mars= 2110 miles
central angle = four degrees of latitude
also π radian = 180°
4° = 4π/180 radian = π/45
length of arc= 2110×3.14/45 =147.3057 miles
four degrees of latitude corresponds to 147.3047 miles
