Answer:
Answer:
Time t=5.5 hours
Explanation:
The first we need to do is to define what speed is:
Physics state that speed is the relation or the measuring of how much space or distance is traveled by an object in a given time
The less time the object takes to move, the faster it is. It indicates then that speed will be a relation between distance and time
To find your answer we will use the previous definition, where t is the time is takes, x is the distance it moves and r is the speed it uses to move.
In this case: [tex]r=x/t[/tex]
For the first scenario we have an object that takes a time t of 9hr with a 14km/h speed r to drive a distance x. We will find how much x is to proceed with the second scenario, this way:
[tex]x=(r)*(t)[/tex]
[tex]x=(14km/h)*(9h)[/tex]
The distance it drives is x=126km
For the second scenario we´re asked to find the time t it takes to drive the same 126km but with a speed r of 23km/h. We will find how much t is this way:
[tex]t=x/r[/tex]
[tex]t=(126km)/(23km/h)[/tex]
Then the new time it takes to drive the same distance with a higher speed will be t=5.5 hours
