A bike travels at a constant speed of [tex]4.0 \, \text{m/s}[/tex] for 5 seconds. How far does it go?
Answer (3)
Taking into account the definition of speed, the bike travels 20 meters.
You have to know that speed is associated with the change in position of a body over time. That is, speed expresses the relationship between the space traveled by an object and the time used for it.
Since speed implies the change of position of an object in space within a certain amount of time, the expression for its calculation is:
s p ee d = t im e d i s t an ce t r a v e l e d
In this case , you know:
speed= 4 s m
distance traveled= ?
time= 5 s
Replacing these values in the speed definition:
4 s m = 5 s d i s t an ce t r a v e l e d
Solving:
4 s m * 5 s= distance traveled
20 m= distance traveled
In summary, the bike travels 20 meters.

The speed of 4m/s means that the bike goes 4 meters for each second of movement. Multiplying this by 5 seconds we have a total distance travelled of 20m.
The bike travels a distance of 20 meters in 5 seconds at a constant speed of 4.0 m/s. This is calculated using the formula distance = speed × time. Thus, 4.0 m/s multiplied by 5 seconds equals 20 meters.
