Howfast must a train travel the next 30 km so that the average speed is 40 km/hr for the entire trip? Q. A car covers 30 km at a uniform speed of 30 km/h. What should be its speed for the next 90 km if the average speed of the entire journey is 60 km/h? Join BYJU'S Learning Program Metersper second. The SI measurement of speed and velocity. This is the number of meters travelled in one second of time. The accompanying acceleration unit is meters per second per second (m/s²). Howmany KMH are in 30 MPH? 30 KMH is equal to how many MPH. How to recalculate 30 Km per hour to Miles per hour? What is the formula to convert from Howfast is 6.09 miles per hour? How fast is 153 miles per hour? How fast is 93400 miles per hour? How fast is 0.63157 kilometer per hour? How fast is 13.68 kilometers per hour? How fast is 41.3 kilometers per hour? How fast is 30.45 meters per second? How fast is 49.20 miles per hour? How fast is 53.40 miles per hour? 6 Saturn travels at 9.69 km/s, or 21,675 miles per hour, which makes it the third slowest planet. 7. Uranus is the second slowest planet with an orbital speed of 6.81 km/s. This equates to 15,233 miles per hour. 8. Neptune travels around the sun at a speed of 5.43 km/s or 12,146 miles per hour. Tocalculate how fast 30 mph is in km/h, you need to know the mph to kmh formula. There are 1.609344 kilometers per mile. Therefore, the formula and the math to convert 30 mph to km/h is as follows: mph × 1.609344 = km/h. 30 × 1.609344 = 48.28032. 30 mphs ≈ 48.28 kmh. Below is an image of a speedometer showing Tocalculate this answer, follow these steps: Calculate total break time: 15 min + 60 min + 15 min = 1 hr 30 min. Subtract this from 8 hours to get 8 - 1:30 = 6 hr 30 min. Multiply Knots Knots are a speed measurement that is nautical miles per hour. This unit is typically used in maritime and aviation. There have historically been different nautical miles used and, thus, different variations of knots. Acar traveling 58.5 km/h is 27.4 m from a barrier when the driver slams on the brakes. The car hits the barrier 2.18 s later. (a) What is the car's constant deceleration magnitude before impact? (b) How fast is Whilehippos may appear to be fat and slow, they can run at 30 km/h on land (19 mph). So despite being the third-largest land mammal on earth, hippos can probably run faster than you. They are very territorial animals and charge at anyone who stands between them and the water. In fact, hippos kill more people than any Howfast is 30 knots? What is 30 knots in miles per hour? 30 knots to mph conversion. Amount. From. To. Calculate. swap units ↺. 30 Knots ≈. 34.523383 Miles per Hour. result rounded. Decimal places. Result in Plain English. 30 knots is equal to about 34.5 miles per hour. In Scientific Notation. 30 1 Light Air. 1 to 3 mph. Direction of wind shown by smoke drift, not by wind vanes. Little if any movement with flags. Wind barely moves tree leaves. Lighttravels at 186,291 miles per second (~300,000 km/s), and the speed of sound in dry air is equal to miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel Thereare 3.6 km/h in m/s. What is meters per second (m/s)? Meters per second is a unit of Speed or Velocity in the Metric System. It measures the number of meters traveled in a second. The symbol for meters per second is m/s and the International spelling for this unit is metres per second. There are 0.2777777778 m/s in km/h. So how fast the average road bike speed is a very broad question. That said here’s a quick answer: the average road bike speed on a flat road is 17-22 mph or 28-35 km/h for men and women who have been cycling regularly for at least a few months. Newer cyclists are slower, and experienced cyclists can get to that speed .
