Speed is a representation of distance travelled over time. Thus to find the time taken you need to divide the distance travelled by the speed. In this case we would need to do 1000 miles divided by 70mph: 1000/70 = approximately 14.2857 Therefore, it would take roughly 14 and a quarter hours to travel 1000 miles at 70mph.
At a constant 70mph it would take 42hrs and 51minutes to travel 3000miles. 3000/70 equals 42.85hrs, .85 times 60 mins/hr equals 51.4 mins.
Under normal conditions it will take a little more than 6 hours.
Time = distance/speed = 324/70 hours = 4.63 hours (approx).
11 hours 30 minutes.
