Time taken = Distance ÷ Speed (or Velocity)
Example : If the average speed for the journey was 56 mph then it would take :-
1421.5 ÷ 56 = 25.38 hours approx.
It would take 3.5 hours to drive 210 miles at 60mph.
To find out how many miles Dan would drive in 5 hours, first determine his driving rate. He drove 605 miles in 11 hours, which gives a rate of approximately 55 miles per hour (605 miles ÷ 11 hours). At that rate, in 5 hours, he would drive about 275 miles (55 miles/hour × 5 hours).
175 miles at 65 miles per hour would be 2.69 hours
The average speed would be 56.75 miles per hours.
About 2.40 hours
At 60 miles per hour it would take about 4 hours.
The time it takes to drive 20 miles depends on the speed at which you are driving. If you are driving at a constant speed of 40 miles per hour, it would take you 0.5 hours to drive 20 miles (20 miles / 40 miles per hour = 0.5 hours). If you are driving at a constant speed of 60 miles per hour, it would take you 0.33 hours to drive 20 miles (20 miles / 60 miles per hour = 0.33 hours).
12 hours
21 hours.
It would take 4.13 hours or 4 hours and about 8 minutes to drive 124 miles driving 30 mph.
60 miles every hour 4000/60 = 66.67 hours
Approximately two hours.
