Anna and John both drive to their new home 600 miles away.
Anna drives the family car at an average speed of 65 mph.
John drives the removal truck at an average speed of 50 mph.
During the trip, Anna stops for a total of 2 hours and 20 minutes, John stops for 90 minutes.
What is the difference in minutes between their arrival times?
:
change 2 hr 20 min to 7%2F3 hrs
change 90 min to 3%2F2 hrs
:
Write a total time equation for each
Truck:600%2F50 + 3%2F2 = 13.5
Car: 600%2F65 + 7%2F3 = 11.56 hrs
----------------------------------------------
Time difference between them: 1.1678 hrs
Change to minutes
60 + .1678(60) = 70.1 min between them
