How much is 100 km in mph?

Answer: 100 km/h is equal to 62.14 mph.

How many kilometers is 45 minutes drive?

The car will travel 45 kms in 45 minutes. Because it's traveling a distance of 60 kms in 60 minutes. Originally Answered: A car travels 100 km in 1 hour.

Why do boats use knots instead of mph?

Cars and trains, known for shorter travel segments, use miles per hour or kilometers per hour. Boats and planes, which often travel longer distances affected by the earth's curvature, use knots. Knots are a more accurate way of predicting how a boat (or a plane) traverses the face of the earth.

Is 30 knots fast for a boat?

But if you're talking about average speed for different boats; yes 30 knot is fast enough to give the thrill.

How long would it take to walk 100 km?

100 kilometers should be covered in 24 hours. The average runner moves at about 10 km/h. A hiker is about half as fast.

How many km is a 1 hour drive?

Speed = distance (60 km) / time (1 hour) = 60km/h.

How many hours drive is 40 km?

A car travelling at a speed of 40 km/ hour can complete a journey in 9 hours.

Why is a knot faster than mph?

One knot equals one nautical mile per hour, or roughly 1.15 statute mph. The term knot dates from the 17th century, when sailors measured the speed of their ship using a device called a “common log.” The common log was a rope with knots at regular intervals, attached to a piece of wood shaped like a slice of pie.

Are knots faster than mph?

1 knot is approximately 1.151 MPH, and 1 MPH is approximately 0.869 knots. To convert from miles per hour, divide the speed by 1.151 to gain the approximate speed in knots. To convert from knots, multiply the speed by 1.151 to gain the approximate speed in miles per hour.

Is 30 mph fast for a boat?

Even under full load conditions, you can go to 30 mph. From my experience, the optimum speed for water sports is 15 to 35 mph. So your pontoon might be a little slow but will be just fine for any water sports you like to do.
