well i can tell your not that good with motors but its 170 mph It depends on what it is mounted on. No boat would do that speed with a 250 cc engine.
the us smart fortwo is is limited to 120 kmh
Distance from Earth varies from 36 million miles (nearest planet after Venus) to over 250 million miles
250
$340 for the alternator for a Jeep Liberty with a $70 labor charge. 250 miles from home, I had no other options and they knew it...
The scale is 83 1/3 miles per inch, times 34.5 inches is 2875 miles.Using decimals would introduce a slight error, so what you may want to do instead is assume a scale 1 inch = 250 miles, times 34.5 is 8625, and then divide by 3 for your actual scale. 8625/3 = 2875
250 (miles) / 70 (mph) = 3.57 (hours)
250 knots = 287.7 mph
It takes 25 hours!
Time = Distance/Speed = 250 miles/50 miles per hour = 5 hours
250 mph= 402.336 kmh. There are 1.609344 kmh in 1 mph, and .6213711922 mph in 1 kmh.
distance=rate*time time=distance/rate time=250 miles/65 miles per hour= 3.845 hours
To get the rate for 250 miles in 5 hours, divide the miles by the hours to get miles per hour, 250 miles/5 hours=50 miles per hour. If you divide 5 hours by 250 miles, you get 0.02 hours per mile, the other unit rate for this set of numbers.
1 knot = 1.15 MPH 250 kts x 1.15 = 287.5 MPH
250 km per hour = 0.04315 miles per second.
@ 250 mph
a 250 ex can get up to 50 miles per hour.
250 knots = 287.694862 miles per hour 250 knots = 463 kilometers per hour
