Actually, I already knew the answer since I've searched it and found out a problem that's similar to my math problem. However, I didn't know how the answer was gotten. This is also involved in physics with the formula of T = D/R (I'm not sure tho). Hoping someone would be able to teach me how. Thank you so much in advance! :) \r<BR>\n" );
