Best Answer

The question, as stated, cannot be answered sensibly. A kilometre is a measure of distance, with dimensions [L]. An hour is a measure of time, with dimensions [T]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

As a simple mental exercise, consider how long it would take you to walk 12 km compared with the time it would take you to drive that distance.

Assuming "3 12" is meant to be 3 1/2 then it will be 28 km.

if you are not moving it is ∞ hours. If on the other hand you are moving with ∞ Km/h then that would be 0 hours.

Answer: 12 km = 7.45645 miles.

12 km = 39370 feet (approx).

Approximately 301.2 miles. distance = rate*time 4 hours, 25 minutes=4+25/60 hrs=4 5/12 hours=53/12 hours 110*(53/12)=5830/12=2915/6 km, or about 485.8 km To convert this to miles, we use the conversion: 1 km is approximately 0.62 miles. 485.8 km*(.62 miles/km)=485.8*.62 miles, which equals approximately 301.2 miles.
