A car travels from City A to City B to the north. It takes 4 hours, and the road mileage is 200 miles. The map shows that the cities are only 80 miles apart (straight-line distance). Calculate the average velocity and give the direction.

:(

To calculate the average velocity of the car, we need to divide the total distance traveled by the total time taken. In this case, the car traveled a road distance of 200 miles in 4 hours. Therefore, the average velocity can be calculated by dividing 200 miles by 4 hours, which gives us:

Average Velocity = 200 miles / 4 hours
Average Velocity = 50 miles per hour

So, the average velocity of the car is 50 miles per hour.

As for the direction, we know that the car traveled from City A to City B, which are to the north. However, the fact that the straight-line distance between the two cities is only 80 miles indicates that the car did not travel in a straight line between them. The deviation from a straight path could be due to road curves, turns, or detours. Therefore, without any further information, we cannot determine the exact direction other than the general northward direction.
