Pam's travel time = 120 miles/60 mph =2 hours
Sue's travel time = 120 miles/50 mph =2.4 hours
Time difference = 2.4 hours - 2 hours = 0.4 hours
To convert 0.4 hours to minutes, recognize that 1 hour = 60 minutes
So, 0.4 hours = (0.4)(60) minutes
= 24 minutes
Answer: D

It took Sue 120/50 = 12/5 = 2 2/5 hours = 2 hours and 24 minutes to drive back from the meeting.
So it took Sue 24 more minutes to travel the distance than it took Pam.
