Answer:
Average speed = 1.2 m/s
Average velocity = 0.4 m/s
Explanation:
Average speed = total distance/total time
Average speed = (40 + 20)/(40 + 10)
Average speed = 60/50
Average speed = 1.2 m/s
Average velocity = displacement/time
Now, she ran 40 m south and ran 20 m back north which is in the direction of where she began the journey.
Thus;
Displacement = 40 - 20 = 20 m
Average velocity = 20/50 = 0.4 m/s
Answer:
The mass of water is 
Explanation:
Given that,
Area of town = 29 km²
Time = 30 min
Height = 2.4 inch
Mass = 103 kg
We know that,
1 m = 39.37 inch
So, 
We need to calculate the volume
Using formula of volume
Put the value into the formula
We need to calculate the mass of water
Using formula of density
Put the value into the formula
Hence, The mass of water is
