Question

A cyclist travels for 90 km. the trip lasts for 5 hours. what is the average speed of the cyclist?

Answer 1

The average speed of the cyclist is 18
`(km)/(hour)`

Step-by-step explanation:

Speed ​​is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. Because it considers direction, it is a vector quantity.

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

`speed=(distance)/(time)`

In this case:

• distance: 90 km
• time: 5 hours

Replacing:

`speed=(90 km)/(5 hours)`

Solving:

`speed=18( km)/( hour)`

The average speed of the cyclist is 18
`(km)/(hour)`
