1.857 hours.
240miles x 1h/70miles= 3.429hours
170 miles with 70 miles/hour: 2 hours 25 minutes 43 seconds
7 hrs 11 minutes and 30 seconds approx
Time = Distance/Speed = 40/70 = 0.5714.. hours = 34.3 minutes
Rate x time = distance 70miles/hour x time = 20 miles 20 miles time = ______________ 70 miles/hour time = 20/70 hour time = .286hours = 17 minutes.
In 1 hour 70 miles traveled So to cover 365 miles, it will take 365/70 = 73/14 = 5 and 3/14 hours = 5.21 hours in decimal
3 hours, 51.43 seconds
time = distance/speed = 70/200 = 0.35 hours, or 0.35 x 60 = 21 minutes
51.43 seconds 70miles/ 1 hour * 1mile/ ?= .014285 hrs .014285 hrs* 60min/ 1hr*60sec/ 1min= 51.43 seconds.
Well, d(istance)=r(ate)*t(ime), so if d=250 miles and r=70 mph, t= 3.6 hours, or 3 hours and 36 minutes.
About 8.25.
If you maintained an average speed of 70 mph, the time to cover 550 miles would be about 7 hours and 51 minutes. You would have to add time for stops, detours and other delays when planning a road trip, though.
