A bus travels from city x due east toward city y. If the bus travels at an average velocity of 90 km/h [E], what will be the displacement of the bus 4.5 h later? SHOW WORK PLEASE!

To find the displacement of the bus, we need to calculate the distance it has traveled and in what direction.

We know that the bus is traveling due east, so its displacement will also be in the east direction. The average velocity of the bus is given as 90 km/h [E], which means it is moving at 90 km/h in the east direction.

To find the distance traveled, we can use the formula:

Distance = Speed × Time

In this case, the speed is 90 km/h and the time is 4.5 hours. We'll plug in these values:

Distance = 90 km/h × 4.5 h

Distance = 405 km

So, the bus will have traveled 405 km in the east direction after 4.5 hours. Therefore, the displacement of the bus will also be 405 km [E].
