This question cannot be answered sensibly. A kilometre is a measure of distance, with dimensions [L]. Miles per hour (mph) is a measure of speed, with dimensions [LT-1]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
120 kilometres = 74.6 miles.
3 mph = 4.8 km per hour
Not too sure of your question but 75 miles is about 120 kilometers
67,108.09 mph
"It is about 240" Actually, 1 mile=1.6km So 120x1.6=193km 240km is about 150mph, not 120
574.8 kmph = 357.1642 mph
80.4672
120 mph = 193.12 km/h
120 kph = 74.6 mph
120
3 mph = 4.8 km per hour
295 kilometers equals 183.30450 mph
88.5139 miles per hour
75 kph = 46.6 mph
Appx. 37.5 mph.
530 mph speed = 853 kph speed (rounded)
70 mph = 112.65408 kilometers per hour
120 mph, which is around 193 kph.
