sin 270° has the value of -1 sweety
If you follow the order of pemdas the answer would be (-24)
1) Circumference of Earth: Diameter x π → 12,800 x π = 40,212.39 km
2) time in Hour = distance/speed → distance = 40,212.39 and speed = 2 Mi/h
1st: convert miles into km : 1 mile = 1.609344 km and 2 miles = 3.218688 km
2nd: convert speed into km/h → speed = 3.218688 km/h
And time in hour = 40,212.39 / 3.218688 → time = 12,493 hours OR in days:
12,493 / 24 = 521 days (OR 104 weeks, including 2 days of rest)
