How many miles on the surface of Mars correspond to four degrees of latitude? (The radius of Mars is approximately 2110 miles.)

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
