You can put this solution on YOUR website!
time = distance/speed
first leg
575/200 = 2.875 hours
..
second leg
325/200 = 1.625 hours
..
stopover time = 0.5 hours
...
total time = 2.875+1.625+0.5= 5 hours
...
total distance = 575+325=900 miles
total time = 5 hours
...
speed = distance /time
900/5= 180 mph is the average speed between Big lake to pine city
