The average velocity of a plane was 600 km/h [N]. How long did it take the plane to travel 120 km?
A. 0.2 min
B. 5 min
C. 12 min
D. 5.0 h
I will be happy to critique your thinking.
5 min
To find the time it took for the plane to travel 120 km, we can use the formula:
Time = Distance / Velocity
In this case, the distance is 120 km and the velocity is 600 km/h. So we can substitute these values into the formula:
Time = 120 km / 600 km/h
By simplifying, we find:
Time = 0.2 hours
Since the question asks for the time in minutes, we know that 1 hour is equal to 60 minutes. Therefore, to convert 0.2 hours to minutes, we multiply by 60:
Time = 0.2 hours x 60 minutes/hour
This gives us:
Time = 12 minutes
So the correct answer is C. 12 min.
