Well, let's see . . . If you can drive 200 miles in each hour, then it should take you 1 hour to drive 200 miles.
5 hours.
200 miles going 60 mph will take about 3 hr 20 min.
36 minutes.
Time taken in hours = 41/200
Time = Distance/Speed = 200/80 = 2.5 hours.
2 hours 13 minutes.
speed divded by time
It will require 3.5 hours to drive that 200 miles.
1 hour, 40 minutes
If you mean 65 miles/hour then just divide. 200 / 65 = 40 / 13 = 3.08 hours
200/72 = 2.778 hours (rounded) = 2hours 46minutes 40seconds
