![]() For example, you drive a car with a speed of 25 mph for 1 h in the city and then reach 70 mph for 3 h on the highway. You should use the average velocity formula if you can divide your route into few segments. Velocity after a certain time of acceleration:įinal velocity = initial velocity + acceleration × timeĪverage velocity formula - the weighted average of velocities:Īverage velocity = (velocity₁ × time₁ + velocity₂ × time₂ + …) / total time In the previous section, we have introduced the basic velocity equation, but as you probably have already realized, there are more equations in the velocity calculator. For example, if you drive a car for a distance of 70 miles in one hour, your average velocity equals 70 mph. The average velocity formula describes the relationship between the length of your route and the time it takes to travel. When an object has only angular velocity, it doesn't displace (the distance is zero), and you can't use the average velocity formula. To learn more about it, head to the speed vs velocity section.Īside from the linear velocity, to which we devoted this calculator, there are also other types of velocity, such as rotational or angular velocity with corresponding physical quantities: rotational kinetic energy, angular acceleration or mass moment of inertia. You have probably noticed that we use words speed and velocity interchangeably, but you can't do it every time. Keep in mind that this velocity formula only works when an object has a constant speed in a constant direction or if you want to find the average velocity over a certain distance (as opposed to the instantaneous velocity). ![]() If you want to put this rule down in the form of a mathematical formula, the velocity equation will be as follows: It is one of the fundamental concepts in classical mechanics that considers the motion of bodies. It took 4 hours for the two to meet if Jake's speed was 15 mph slower than Brian's.Velocity definition states that it is the rate of change of the object's position as a function of time. What is his average speed for the entire trip?īrian and Jake left their homes 500 miles apart and drove straight toward each other. he then traveled back home on the same path at a speed of 24 miles per hour. Starting at home, Tony traveled uphill to the store for 45 minutes at 8 miles per hour. Use the following facts to convert this units: 1 meter = 39.37 inches, 1 mile = 1609 m, 1 hour = 60 minutes Express it in miles per hour, correct to three significant figures. The speed of the mail train is 1370 meters per minute. When did the faster caravan run slower? How far from the oasis? Two hours later, a second caravan followed her at 2.5 miles per hour. After how many hours will the cars be 30 miles apart?Īt 6:00 in the morning, a caravan set out of the oasis at a speed of 1.5 miles per hour. Find how long it takes her to drive round-trip if she averages 40 mph.Īt 9:00 AM, two cars started from the same town and traveled at a rate of 35 miles per hour, and the other car traveled at a speed of 40 miles per hour. She must go to the law library in city B to get a document. If John starts running at 10:00 AM, and Lucy starts running at 10:30 AM, what time will they meet? (as soon as possible)Ī woman works at a law firm in city A, about 50 miles from city B. ![]() If John has a running speed of 3.5miles per hour and Lucy has a speed of 5 miles per hour. For how long will the first car traveled when the second car overtakes it? A second car begins an hour later, along the same path traveling at 70 mph. How many hours did it take Ed to drive to New Jersey?Ī car begins heading along a path at 50 mph. How far can she walk in 2 hours 45 minutes?Įd drove to New Jersey at 30mph. Lucie can walk about 3 4/5 miles each hour. ![]() If the speed is increased by 30 miles per hour, find the time taken by the truck to cover the same distance in hours. Find the driver's time.Ī truck covers a particular distance in 3 hours with a speed of 60 miles per hour. What is the unit rate that this train is traveling per hour? Write in miles per hour.Ī race car driver won a 500-mile race with a speed of 116.3 miles per hour. ![]() After an eight-hour flight is at its destination, how far did the plane fly?Ī train can travel 1136 miles in 4 hours. Conversion of a velocity unit in word math problems and questionsĪ plane is flying at the rate of 350 mph. ![]()
