Let Speed at which Sue swims be x laps/hr
As per the question stem, Joel swims 50% faster therefore Speed at which Joel swims is 1.5x laps/hr
The no of laps sue swims in 80 minutes i.e the distance covered by sue in 80 mins is given by Speed of Sue * Time = x laps/hr *(80/60)hrs=1.3333x
The no of laps Joel swims in 60 mins is given similarly by Speed of Joel*Time = 1.5x laps/hr*(60/60)hrs= 1.5x
Clearly quantity B is greater than A hence Option B is the answer.
