You're unlikely to become a faster reader in that time. You may have to face up to sacrificing some questions as guesses, so if you blind guess an option (say option 2 for all that set) for a passage that is really long that will buy you some time for the other shorter passages. You can always flag and come back to it at the end if there is time, but to me it doesn't make sense to rush all the questions a bit and not be sure on your answers, when you could completely blind guess and flag one or two large sections quickly buying you time for the other sections.
