Taking into account the definition of speed, the average speed of the car in the trip is 57.14 .
Speed is a physical magnitude that relates the displacement of an object and the time it takes to make this change in position.
So, the speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:
Speed has units of , such as
or
.
In this case, you know that:
- displacement= 200 miles
- time= 3.5 hours
Replacing in the definition of speed:
<u><em>speed= 57.14 </em></u>
Finally, the average speed of the car in the trip is 57.14 .
