Help: Force of Resistance

[buffgilville]

A golfer misjudges a putt, sending the ball a fraction 0.67 of the distance to the hole. If the force of resistance due to the grass is constant, by what fraction should he increase the speed to make the putt?

I have no clue how to do this type of problem. Someone please help. Thanks

Well, if the golfer has already covered 0.67fraction of the distance to the whole, that equates to 2/3 of the total distance.

if he has already covered 2/3's of the distance, that means that 1/3 is left to go.

and since he was able to go 2/3 of the distance with his inital speed, how should he adjust it to only go 1/3 of the distance for his next putt?

don't know if this clarifies it good enough for you, im not really sure how to explain it without giving the answer away.
