use the formula (dlong * cos lat)
dlong in this case is 10. so in case (a) and (c), the answer is the same coz of same latitude(cos 60 = 1/2 is same for north and south and cos 30 = sqrt(3)/2 = for N and S lats). So its either (b) or (d). Will let you know the answer soon as its 4.30 am in my corner of the world and I dont know where my scientific calculator is.
And Monsieur airborneforever,
If you dont know the answer, you can rather shut up. If you cant help an other person with your knowledge, that knowledge is useless.
Cheers,
