In how many ways can 3 girls divide 10 pennies if each must en dup with at least one penny?
I need a step by step help with this problem ;
An office building has 33 floors, each 10 feet high, and elevators that travel at a constant speed. If it takes 10 seconds for an elevator to go from the first floor to the fifth floor, how long will it take an elevator to go from the fifth floor to the middle floor?
