2.55hours. Divide 140 by 55.
38/55 = 0.69 hours = about 41.5 minutes
It would take 0.12727272727... hours, or 7.6363636363... minutes
About 1 hour 49 minutes.
1 hour 27 minutes at a constant 55 mph, excluding speed changes, delays or stops.
about a 123 ft 60 mph is 134 take the sqaure of the mph and that will give u the distance
it depends on how hard u stop
It depends on the condition of the brakes and the road.
Stopping Distance = about 206.25 feet at 55 mph
If you drove non-stop at a constant speed of 55 mph, it would take about 32 minutes and 43 seconds.
About 8 hours 30 minutes at a constant 55 mph.
228 feet
Exactly 1 hour
Time = Distance/Speed = 600/55 = 10.9090.. provided you do not stop for refuelling, or comfort stops, or rest or anything.
If you drove non-stop at a constant speed of 55 mph, it would take about 54 minutes and 32 seconds.
21 miles / 55 mph = 0.38 hours, or 23 minutes
This depends on how fast you drive. Assuming you are driving 55 mph and we know that the circumference of the earth is 24901.55 mi, we can assume that it would take, 24901.55 / 55 = 452.755 hr or 18.9 days non stop at a constant 55 mph.
