No rockets can fly to the moon due to the deceleration of earth gravity?

fly away from earth at 25,000 miles per hour, will be decelerated by gravity to zero speed within an hour.
no rockets able to fly to the moon from earth under 1 g deceleration.
am i correct?
Quoting: Anonymous Coward 59686777 Yep, at 25,000 mph you would not escape the gravitational pull... You have to achieve at least 7 miles per second or more to do that. That means 25,200 mph or more... at 50,000 miles per hour, still will be decelerate to zero within 2 hours. Nope. You aren't accounting for the fact that as you get farther away the strength of gravity decreases. still, continuing decelerating, am i correct? can you calculate it? my math sucks.
