## What is the speed of a car that is moving at 50 mph in kilometers per hour KPH )?

While the most economical driving speed changes with every vehicle, the general consensus is that it is around 50 mph (80 km/h).

## How do you find the number of revolutions per minute the wheels are rotating?

Calculate the wheel speed in revolutions per minute. To do this, use the formula: revolutions per minute = speed in meters per minute / circumference in meters.

## How much is 100 km in miles per hour?

Answer: 100 km/h is equal to 62.14 mph So, 100 km/h is equal to 62.14 miles per hour. You can refer metric conversion chart for easy calculations and more clarity.

## What does the speed of a car is 50 km h mean?

Expert-Verified Answer Car is moving with the speed of 50 km per hour means that the car covers a distance of 50 km in 1 hour. Uniform speed: If a body covers equal distance in equal interval of time, then body is said to be moving with a uniform speed.

## What is the formula of revolution?

In covering a distance s metres, a circular wheel of radius r metres makes s2πr revolutions.

## What is the formula for speed of rotation in RPM?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

## What is the formula for calculating rotational speed?

The formula for rotational speed is Rotational speed = rotations / time but linear speed = distance / time.

## What is 5 minutes per km in miles per hour?

Kilometers Per Hour | Miles Per Hour | Minutes Per Kilometers |
---|---|---|

12.00kph | 7.46mph |
5:00 |

12.10kph | 7.52mph | 4:58 |

12.20kph | 7.58mph | 4:55 |

12.30kph | 7.64mph | 4:53 |

## How much hour is 1 km?

Kilometres per hour is a unit of measurement, which measures speed or velocity. The unit symbol is km/h or km·h−1. By definition, an object travelling at a speed of 1 km/h in a straight line for 1 hour moves 1 kilometre.

## How do you convert kilometers to miles per hour?

## What is the average speed of a car moving at a speed of 50 km hr returns with a speed of 40 km hr?

Average speed=1+1(1/50)+(1/40)=44.44m/s.

## What is the average speed of the car travels at a speed of 50 km hr for 30 minutes and then 70 km hr for next 45 minutes

The correct Answer is:56.66 km/hr by Physics experts to help you in doubts & scoring excellent marks in Class 11 exams.

## How do you calculate the speed of a car in km h?

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.

## Can a car moving with a speed of 50 km per hour be stopped?

A car moving with a speed of 50 km/hr, can be stopped by applying brakes after at least 6 m.
