How long does it take a packet

How long does it take a packet of length 1, 000 bytes to propagate over a link of distance 2, 500 km, propagation speed 2.5 ·10⁸ m/s, and transmission rate 2 Mbps? More generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on transmission rate?
