you can make these experiment right now 1.-grab a piece fo paper and your keys 2.-throw them from the same altitude to the floor the keys land first right
3.-now grab the paper and make it a small ball 4.- throw them again which land first now ??? these is caused because the paper cut the air and that slow it at first when you make it a ball the paper can't cut the air and go at the same speed than your keys.

these is the same experiment that do Galileo Galilei in the pisa tower

Ignoring drag... the same time. The problem should mention this assumption.
