## Amazon EFI Interview Question

Software Engineer / Developerstheta = 30Y - 6X.

where 30 and 6 are the angles covered in 1 hr and 1 min respectively.

thus if time is 1hr 1 min. Then Y = 1, X = 1

so theta = 30-6 = 25deg

If X is 1 min then Y = 30/60 = 0.5

so theta = 30*0.5 - 6 as state above.

This accounts for the change in hour hand for every minute (There is 0.5 degree change in the hour hand for each minute).
