At the weekend it takes 8 mins and 4 on week days. That's half, so the difference is 50% of the weekend time.
The other way of looking at it is 4 mins on weekdays and 8 mins at the weekend so that is a difference of 100% of the weekday time.
It appears to be a badly worded question. Stating what the percentage difference relates to qualifies what you are talking about and hence either of the above answers, fully qualified, is valid.
