Maths/puzzle question

So, I'm doing a foundation paper. I don't understand this question. It says Seeta did a puzzle in 3 minutes 45 seconds. Ninal did the same puzzle in 7 minutes and 28 seconds.
Seeta says "I did the puzzle in less than half the time Ninal did the puzzle."
b. Is seeta right?

3 minutes + 3 minutes = 6 minutes
so the 1 minute and 28seconds left of Ninals time = 88 seconds
if you times the 45 by 2 it =90 not 88.
So Seeta if wrong.
