Lakeview is 101 miles from Springfield. Irania must go to the law library in Springfield to get a document for the law firm for which she works. Find how long it takes her to drive round-trip if she averages 49 mph.

Approximately 4.1224 hours

4.1224 hours = 4 hours, 7 minutes, 21 seconds approximately

Work Shown:

d = distance = 2*101 = 202 miles

r = rate or speed = 49 mph

t = time = unknown

d = r*t

202 = 49*t

49t = 202

t = 202/49

t = 4.1224 hours approximately

If you want to convert to hours,minutes,seconds, then...

4.1224 hours = 4 hours + 0.1224 hours

4.1224 hours = 4 hours + (0.1224*60) min

4.1224 hours = 4 hours + 7.344 min

4.1224 hours = 4 hours + 7 min + 0.344 min

4.1224 hours = 4 hours + 7 min + (0.344*60) sec

4.1224 hours = 4 hours + 7 min + 20.64 sec

4.1224 hours = 4 hours + 7 min + 21 sec approximate

4.1224 hours = 4 hours, 7 min, 21 sec also approximate

Note: this time value is driving time only. It does not take into account any time spent at the law library or any other stops.
