# What does a car moving at an average speed of 55.0 mi h for 4.25 h has traveled?

## What does a car moving at an average speed of 55.0 mi h for 4.25 h has traveled?

Answer and Explanation: This means the car has travelled a distance of 234 mi in the given time interval.

## 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 for the time it was moving?

It is calculated by dividing the total distance something travels by the total amount of time it spends traveling. For example, one can consider the car from earlier. If the car travels 70 miles in 2 hours, it would have an average speed of 70 / 2 = 35 miles per hour.

## How to calculate speed?

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

## How to calculate average velocity?

Average velocity is calculated by dividing your displacement (a vector pointing from your initial position to your final position) by the total time; average speed is calculated by dividing the total distance you traveled by the total time.

## What is the formula for average velocity Class 9?

Average velocity is calculated by the formula V = D/t, where V equals the average velocity, D equals total displacement and t equals total time.

## What is the speed of a car travels 60 km in 45 minutes?

time taken by car = 45min. = 45/60 hr = 3/4 hr. speed = 60*4/3 = 80km/hr.

## What is the average speed of the car at a constant speed of 60 km h for 1 km and 40 km h for the next 1 km?

Answer – The average speed of the car is 48 Km/hr. Q. Q. A car covers 160 km at a speed of 40 km/hr and the next 120 km at a speed of 60 km/hr calculate its average speed.

## What is the formula for average speed with two speeds?

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. Case 2 – When the time taken is constant: Average speed = (x + y)/2; Where, x and y are the two speeds at which we traveled for the same time. Examples: Q1.

## What is the SI unit of acceleration?

Therefore, the SI unit of acceleration is the meter per second squared or (ms−2).

## What is called average speed?

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.

## What is the meant by the average speed of a moving car is 60 km h?

When we say that the car travels at an average speed of 60 km/h it does not mean that the car would be moving with the speed of 60 km/h throughout the journey. The actual speed of the car may be less than or greater than the average speed at a particular instant of time.

## How do you calculate the speed of a car that went?

The formula for speed and distance is the same for a car as any other object: distance ÷ time.

It goes 66 km.
