Question

Suppose John found his longitude to be 90.721°. What is this measure in degrees, minutes, and seconds? If needed, round your seconds to the nearest tenth. Remember that 1° = 60' and 1' = 60".

Answer 1

Answer: 90 degrees, 43 minutes, 16 seconds

Step-by-step explanation: To convert from decimal degrees to degrees minutes and seconds, the whole number part which is 90 is the degree, then multiplying the decimal part (0.721) by 60 gives the minutes which is 43 and finally multiplying the remaining decimal (0.26) by 60 gives the seconds which is approximately equal to 16
