The units are incompatible as a direct conversion. Given an average speed of travel it could be calculated how much time it would take to travel a given distance.
70 x 2 = 140 milesNote: multiply the MPH by the hours, as shown above.
maths. if you drive constant at 70MPH for 2 hours that's means 70 x 2 = 140 miles
3 hours by car. About 140 miles.
In 2 hours, you will travel 140 miles. The extra 12 miles will take 10 minutes 28 seconds.
If you average 65 miles per hour for the entire distance your driving time would be about 2 hours and 9 minutes.
(3 hours) x (60 miles/hour) = 180 miles (2 hours) x (70 miles/hour) = 140 miles Total = 180 + 140 = 320 miles
If you start at mile marker 255 and drive to mile marker 115, you are covering a distance of 140 miles (255 - 115 = 140). At a speed of 70 miles per hour, it will take you 2 hours to complete the journey (140 miles ÷ 70 mph = 2 hours).
140 kilometers is about 87 miles.
140 miles = 225.31 kilometres
Divide 140 by 20 and you get 7So he was going 7 miles per hour.The doublecheck:If you ride at 7 miles per hour for 20 hours you go 140 miles (7 x 20).
140 hours is equal to 5.83 days.
140 miles = 225.3 km
