Most of the techniques I have discovered to time align two signals requires them to be sampled at the same rate. I am aware of the resample() function on matlab but I have a signal sampled at 60 Hz and the other at 200 Hz and I must of course use a rational fraction. Is there a way around this?

Around what, specifically? What do you think you want to resample to?

According to the documentation on resample, p and q simply have to be integers, and 60 and 200 meet those requirements. It is probably more reliable to downsample the signal sampled at 200 Hz to 60 Hz sampling.
