Time taken by palm = 120/60 =2 hrs
time taken by sue =120/50= 2.4hr

difference = 2.4-2 =0.4 hrs = 24 minutes

Travel time = distance/speed
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

It took Pam 120/60 = 2 hours to drive to the meeting

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.
