Soo what do you need help with? It seems pretty easy. I can help you if you want.
Total distance covered = 5 x 30 = 150 miles
Angle of travel with respect to south pole = 180 - 164°56' = 15°4'
Let the distance southwards covered be x, then
cos 15°4' = x/150
Thus, x = 150 cos 15°4' = 144.84
Therefore, the distance covered southwards = 145 miles to the nearest mile.
If the price for the adult ticket is $2.75 more than the child ticket, the adult ticket would be x + $2.75
