Radar signals is essentially electromagnetic radiation emitted at specific intervals. The radar, or radio signals would therefore travel at the speed of electromagnetic radiation in vacuum, which is 299792458m/s exactly.
40000000 divided by 299792458 = 0.13342563807926081983023068578997 seconds - a little more than one tenth of a second.
