The meaning of execute permission for a directory is the ability to look up file names inside that directory.
Without execute permission on the directory, you can't stat, open, rename, delete, or descend into subdirectories inside that directory.
The only thing you can do is see the list of which filenames exist, and then only if you have read permission (and read but not execute is a strange set of permissions to have for a directory).
If you are not owner of the given directory, become a owner by using,
sudo chown username /path/to/directory
Or better way is to add user to a group,
sudo usermod -a -G groupName userName
for getting execute permission use,
sudo chmod a+x /path/to/dir
