4. A cheetah can run 12 km in 0.9 hrs. Calculate its velocity.
Velocity= Distance/Time
= 12/0.9 (km/hrs)
10.8
To calculate the velocity of the cheetah, we need to use the formula:
Velocity = Distance / Time
In this case, the distance the cheetah runs is given as 12 km, and the time it takes is 0.9 hours.
Plugging these values into the formula, we get:
Velocity = 12 km / 0.9 hours
To simplify the calculation, we can convert 0.9 hours to minutes. Since there are 60 minutes in 1 hour, we can multiply 0.9 by 60:
0.9 hours * 60 minutes/hour = 54 minutes
So the cheetah runs 12 km in 54 minutes.
Now, we can calculate the velocity by dividing the distance by the time:
Velocity = 12 km / 54 minutes
To convert minutes to hours, we divide by 60:
54 minutes / 60 = 0.9 hours
Now, we can substitute this value back into the velocity formula:
Velocity = 12 km / 0.9 hours
Calculating this, we get:
Velocity = 13.33 km/hr
Therefore, the velocity of the cheetah is approximately 13.33 km/hr.
