One way trip = 85 miles
Round trip = 85 * 2 = 170 miles
Time = Distance / speed = 170 / 59 = 2.88 etc.
The round-trip from Lakeview to Springfield take approximately 3 hours.

Lake view 85 miles from springfield
round trip = 170 miles
average speed 59 mph
divide 170/59
so her time would be 2.88 hours or 2 hours and 52 minutes

Helga needs to go 85 miles and come back 85 miles. So the total distance she needs to travel is 85+85=170 miles.
If the total distance is 170 miles, and her average speed is 59 mph, then the time (time=distance/speed) will be 170/59. So divide 170 by 59, which is equal to 2.88 hours, or you can round it off to 2.9 hours, which meand approximately three hours for the round-trip.

Average Speed = Total Distance/Total Time
Hence, Total Time = Total Distance/Average Speed
The total distance = 170 m
Avarage Speed = 59 mph
Therefore, total time = 170/59 = 2.88135593 hrs
