Paste your presentation script to see its delivery time at several speaking rates, so you can cut it to the slot before you rehearse rather than after you overrun.
time = words ÷ speaking rate
130 words per minute is a common presentation pace. Nerves push most people faster on the day, and dense or numerical material needs to be delivered slower.

Most presentation rubrics penalise going over the slot, and many chairs simply stop you, which loses the conclusion — usually the part carrying the argument. Writing to 80% of the slot leaves room for a question, a technical problem and the pause you will need after the third slide. A twelve-minute script in a ten-minute slot is not ambitious, it is an unfinished presentation.
If the number is not the part you are stuck on, that is what the service is for — a specialist who explains the working, not just the answer.
