Hello from MrBillDoesMath!
Answer:
53 degrees, 27 minutes, 5 seconds
(53 goes in the first box on the left; 27 in the middle box; 5 in the rightmost box)
Discussion:
Sum of the degrees = 20 + 30 + 2 = 52 degrees
Sum of the minutes = 15 + 41 + 30 = 86 minutes = 1 degree, 26 minutes
Sum of the seconds = 18 + 32 + 15 = 65 seconds = 1 minute, 5 seconds
So adding all of this up gives a grand sum of
(52 degrees) + ( 1 degree, 26 minutes) + (1 minute, 5 second) =
53 degrees, 27 minutes, 5 seconds
Thank you,
MrB
