A car goes 10 km in 5 minutes when its average velocity is 80 km/hr. true or false
Compere two results
v(ave)=s/t=10000/5•60=...
and
v =80000/3600 =...
To determine if the statement is true or false, we need to verify the given information.
Average velocity is defined as the total displacement divided by the total time taken.
We are given that the car traveled 10 km in 5 minutes. This gives us the displacement.
First, let's convert the time from minutes to hours:
5 minutes = 5/60 hours = 1/12 hours
Total displacement = 10 km
Total time = 1/12 hours
Using the formula for average velocity, we have:
Average velocity = Total displacement / Total time
= 10 km / (1/12) hours
= 10 km * (12/1) hours
= 120 km/h
Now let's compare the calculated average velocity with the given average velocity of 80 km/hr.
120 km/hr is not equal to 80 km/hr.
Therefore, the statement "A car goes 10 km in 5 minutes when its average velocity is 80 km/hr" is FALSE.
