Depends on how fast you travel...
390.9 km = 245 miles. About 4 hours by car.
245 miles
3.5 x 70 mph = 245 Miles
3.5*70 = 245 miles
Divide 245 miles by 3.5 hours.That gives 245/3.5 = [you can work this out] miles per hour.
245 kilometers is 152.24 miles.
About 245 road miles.
2 hour
The answer would depend on the speed you are going. To find the answer, divide the number of miles needed to travel (245) by the average miles per hour of the vehicle. Examples: At 1 mile per hour, the answer is 245 hours. At 2 mph the answer is 122.5 hours. At 5 mph the answer is 49 hours. At 24.5 mph it would take 10 hours. At 245 miles per hour it would take 1 hour.
About 152 miles or 245 kilometres.
245/80=a little over 3 hours.
3.5 hours.
