Hello,
Are suppose to use "gain" or "save" in this case? :
-I'm going to move house, that way I'll be 25 km closer to work, I'll save /gain 15 minutes of driving.
Thank you
W
If anything, to gain 15 minutes of driving would mean you drove for a longer time, not a shorter time.
Will, it's "are we supposed", not "are suppose".
