Question

What is the average speed of 3043 km from houston to seattle in 5.5 hours rounded to the nearest hundredth

Answer 1

The average speed is 553.27
`(km)/(hour)`

Step-by-step explanation:

Speed is the physical magnitude that shows and expresses the variation in position of an object and as a function of time. In other words, the speed relates the distance traveled by an object in the unit of time.

The average speed is the quotient of the space traveled by an object and the time it takes to cover the path:

`speed=(distance)/(time)`

In this case:

• distance: 3,043 km
• time: 5.5 hours

So, replacing in the definition of speed:

`speed=(3,043 km)/(5.5 hours)`

Solving:

speed= 553.27
`(km)/(hour)`

The average speed is 553.27
`(km)/(hour)`
