TRUE
As many as you want. More miles will take more time. For every hour you spend doing it, you can travel 70 miles.
1 mph = 1.609344 kphSo just multiply your speed in mph by 1.6 (or you can use more decimal places to get a more accurate answer).so for example, 55 mph x 1.6 = 88 kph
1.5 miles in 12 minutes = 7.5 miles/hour = 12.07kilometers/hour, or more
22 knots=25.3171479 miles per hour

21 feet per second is approximately 14 miles per hour.
The other person said: 1 metre/second = 0.172603109 miles/hr ∴ 340 metres/second = 58.68505706 miles/hr Let's see why that is wrong. 1 metre/second = 60 metres/minute =3600 metres/hour 1 statute mile = 1 609.344 metres, therefore 1m/s = 3600 / 1609.344 per hour = 2.236 miles per hour therefore 340m/s = 340 x 2.236 =760.558 miles per hour Now: idiot check, do you break the sound barrier in your car when driving 59 miles per hour? No. Is the speed of sound more like 750 to 800 miles per hour (depending on the temperature)? Yes.
"41 knots" means 41 nautical miles per hour. In terms of a few other more familiar units: -- 75.9 kilometers per hour -- 69.2 feet per second -- 47.18 miles per hour

Not only is the question constructed meaninglessly, but it includes a completely false statement of 'fact'. The speed of light is not 300.000 miles an hour. It's more like 300,000 kilometers per second.
Very fast. At that speed you are covering more than 1/4 of a mile every second.
By definition, light travels 299,792,458 meters per second. This gives 299,792.458 kilometers per second. Multiplying by 60 gives 17,987,547.48 kilometers per minute, and multiplying again by 60 gives the distance traveled per hour. It is 1,079,252,848.8 km/h. See the related link for more information.
