There is multiple ways to make money at any level and there is no real 'best way', also not knowing what skill you are level 60 in i assume it is combat so i will just say the possible ways to make money using combat in a free to play world.
1. kill cows, take cowhides, sell on grand exchange usually prices around 100gp each so, kill 100 cows you make around 10k
2. kill hill giants, take big bones, sell on grand exchange usually prices around 3-400gp each so kill 100 you make 30-40k
3. kill lesser demons, these are quite hard to kill and are on karamja however you can fish on the pier located there and cook your food and keep repeating trips, these drops rune med helms and other items which can be of some value but its rare they do and it could take a few trips.
4. the giant cockroaches between barbarian village and Edgevil you will need food to make a decent trip to these since they can hit often, however they are worth the risk as they can drop, rune scimitar, rune plate, rune legs, rune kite and others.
There's many more ways to make money but it would take too long to say them all and i was just naming a few combat methods for free to play in case you are not a member.
You just attack a lot. Note that there are different attack styles; one of them gives you only attack experience. If you select this, you will get more attack experience, but if you select the attack style that gives you shared experience, the experience will be shared among attack, defense, strength. It really depends on your priorities which you choose, but if you specifically want to train attack, choose the option that gives you "attack" experience.

you can't
Try mining.
if you have a combat of lvl 70+ It it suggested you kill green dragons they make about a mil an hour
Start crafting, woodcutting, or hunting.
Do woodcutting once lvl 60 you can get millions in a week if you play a lot
hill giants and pick up their bones them bank them
Check related question if you can find some you want to do to make money.
Use a battleaxe and no life.
bronze dragons
depends on what level you are but if your lvl 68 + i would chop ivy (Members Only) but it is 332-333 exp an ivy that's if you want to get 99 woodcutting fast and not make money
lvl 79
cut willows. they give a good amount of exp but they do not make a lot of money. If you have other questions, add hy839 on your friends list and ask. I'm a lvl 126......
Edgeville dungeon
