How do you find the rate in mph?
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour.
How do you find average speed when distance is constant?
1. Average Speed. Case 1 – When the distance is constant: Average speed = 2xy/x+y; Where, x and y are the two speeds at which the same distance has been covered.
What is the formula for speed rate?
Algebraic Rate of Speed Formulas distance = rate x time. As long as you divide the same non-zero elements of each side of an equation, it remains true.
How much time will be taken to cover a distance of 450 km at a speed of 50 km per hour?
How much time will be taken to cover a distance of 450 km at a speed of 50 km per hour? Solution: Time taken to cover 50 km = 1 hour.
How long will it take to travel 432 Kilometres at an average speed of 96 Kilometres per hour?
question. It will take 4.5 hours to travel 432 kilometers at an average speed of 96 kilometers per hour.
How do you find the average speed between two distances?
Average Speed = 2ab/(a + b) Applicable when one travels at speed a for half the distance and speed b for other half of the distance. In this case, average speed is the harmonic mean of the two speeds.
How do you calculate rate per 100,000?
A crime rate is calculated by dividing the number of reported crimes by the total population. The result is then multiplied by 100,000. For example, in 2014 there were 48,650 robberies in California and the population was 38,499,378. This equals a robbery crime rate of 126.4 per 100,000.
What is a rate per 100?
“Rate” simply means the number of things per some other number, usually 100 or 1,000 or some other multiple of 10. A percentage is a rate per 100.
How do you solve for constant rate problems?
All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T).
How much time will a car take to cover a distance of 300 km if the speed of the car is 50 km h?
Therefore, time taken to cover 300 km is 5 hours.
How long will it take to cover a distance of 330 kilometers?
6 hours take to cover a distance of 330 km.
How long will it take to travel 210 km 50 km/h The answer must be converted into hours and minutes?
question. Answer: 4.2 hr will take to travel 210 km at 50 km/hr.
Is constant speed the same as velocity?
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
Is constant speed the same as average speed?
What is the difference between constant, instantaneous, and average speed? constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.
What is 300 km/h in miles per hour?
What is 300 kilometers per hour in miles per hour? 300 km/h to mph conversion. A kilometer per hour is a unit of speed. Something traveling at one kilometer per hour is traveling about 0.278 meters per second, or about 0.621 miles per hour.
What is the formula for rate and distance?
distance = speed x time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.
What is the average speed of 2450 miles per hour?
The answer is 2450 / 5 = 490 mph (miles per hour) average speed. If you want the result in km/h, you can convert from miles to km to get 788.58 km/h. Distance formula. The formula for distance, if you know time (duration) and the average speed, is: d = v x t
How do you calculate average speed in miles per hour?
Then you need to know the travel time. Make sure you subtract any rests or stops you made from the total trip duration. If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph).
