Since the two distances are equal, the average is (40 mph + 60 mph)/2 = 50 mph.
It depends on the speed that you can drive at. Time = Distance/Average speed
The basic formula is: distance = speed x time In this case, you have to divide the distance by the speed.
That depends on the average speed. Choose an appropriate speed, then divide the distance by the speed.
Average speed = total distance / total time Therefore, total time = total distance / average speed = 420 miles / 60 miles per hour = 7 hours It takes 7 hours to drive 420 miles at 60 miles per hour
Depends on the average speed: time taken is distance divided by average speed or time = distance / speed For example driving at 49 miles per hour: time = 98/49 = 2 hours
To find how long it will take to drive any distance, the average speed must be known. Once the speed is known, one can take the distance and put it over the speed to determine the amount of time it takes to drive somewhere. For example, if you are going an average of 60 miles per hour, you can find that it will take 4 hours to drive to your destination.
It depends on the speed at which you drive. If your average speed is 60 miles per hour then it would take you about 17 hours to cover that distance.
It takes(1,000)/(your average driving speed in mph) hours
Time = Distance/Speed = 346/85 = 4.07 hours, provided you can maintain that average speed.Time = Distance/Speed = 346/85 = 4.07 hours, provided you can maintain that average speed.Time = Distance/Speed = 346/85 = 4.07 hours, provided you can maintain that average speed.Time = Distance/Speed = 346/85 = 4.07 hours, provided you can maintain that average speed.
Time = Distance/Speed = 13.77 hours - assuming the average speed can be maintained for that length of time.
With no indication of average speed, it is impossible to convert distance travelled into time taken.
That would depend on the speed you were going at. Since one never drives at a constant speed, it would have to be an average speed.
