Steve's Elevator = S, travels at rate of 57 floors per min, so for every second S climbs 57/60 floors =>19/20 floors
Joyce Elevator = J, travels at the rate of 63 floors per min, so for every second J travels 63/60 floors => 21/20 floors

In twenty seconds, S would have climbed 19 floors (30th floor) and J would have traveled 21 floors (30th floor)
