The students in Mr. Smith's literature class are assigned to read a 900-page book. Three students, Elena, David, and Fiona, are part of this class. Elena reads a page in 50 seconds, David reads a page in 75 seconds, and Fiona reads a page in 40 seconds. David and Fiona decide on a 'team reading' approach where Fiona starts from page 1 and David starts from where Fiona stops through page 900. Determine the last page Fiona should read such that both spend an equal amount of time reading.
