    Velocity
In summary, the person traveled for a total of 93.7 minutes, with speeds of 82.7 km/h, 97.7 km/h, and 39.9 km/h, and spent 17.2 min eating lunch and buying gas. The distance between the initial and final cities can be found by using the formula v = d / t, and the average speed for the entire trip can be calculated by taking the total distance and dividing it by the total time.

a person travels by car from one city to another with different constant speeds between pair of cities, she drives for 34.2 minutes at 82.7 km/h, 11.1 min at 97.7 km/h, and 48.4 min at 39.9 km/h and spends 17.2 min eating lunch and buying gas. find the distance between initial and final cities along this route. find average speed for this trip

So what's the problem, and by that I mean, where are you stuck? On the first part of the problem, or the second? Please show us your work so far, so we can help you out.

Hint: the first part of the problem is really straightforward. We know how fast she traveled and how long she traveled for at that speed, so we can easily calculate how far she went during that part of the trip.

Were there any directions given for the velocity? Or are you assuming that this all happens in a straight line?
 
  • #4
there is no directions given for the velocity and I am stuck at the first question. is this an weighted average problem?
 
  • #5
For the first question just use:

v = d / t
 

1. What is help velocity distance?

Help velocity distance is a term used to describe the speed at which an object or person travels while providing assistance or aid to someone else. It takes into account the distance covered and the time it takes to cover that distance while helping someone.

2. How is help velocity distance calculated?

Help velocity distance is calculated by dividing the distance covered while providing help by the time it takes to cover that distance. The resulting value is the average speed at which help was given.

3. Can help velocity distance be negative?

No, help velocity distance cannot be negative. It is always a positive value because it represents the speed at which help was given, regardless of the direction of movement.

4. How is help velocity distance different from regular velocity?

Help velocity distance differs from regular velocity in that it takes into account the distance covered while providing help, rather than just the distance traveled. It also focuses on the speed at which help was given, rather than the overall speed of the object or person.

5. What factors can affect help velocity distance?

Some factors that can affect help velocity distance include the weight of the object or person being helped, the terrain or surface being traveled on, and the amount of assistance being provided. Other factors such as wind or incline can also impact the help velocity distance.
