city b is north of city a and the 400 mile trip by care takes 8 the cities are 320 miles apart in a straight line what is the velocity of a trip from city a to city b

I assume you mean 8 hours.

Velocity is the displacement /time and direction
Here that is 320/8 or 40 mph North

The 400 zigging and zagging is irrelevant for velocity but important if you wanted speed instead of velocity

To calculate the velocity of a trip from City A to City B, we need to determine both the distance and the time taken for the trip.

Given information:
- The trip by car takes 8 hours.
- The cities are 320 miles apart in a straight line.

Since the cities are 320 miles apart in a straight line, we can assume that the distance traveled by the car is also 320 miles.

Now that we have the distance (320 miles) and the time taken (8 hours), we can calculate the velocity using the formula:

Velocity = Distance / Time

Thus, the velocity of the trip from City A to City B would be:

Velocity = 320 miles / 8 hours = 40 miles per hour
