The rate of running in miles per hour of Julia is 7.5 mile per hour
Velocity:
The rate of change of distance is measured as velocity of that object
The formula for velocity is
velocity = \(\frac{distance}{time}\)
How to calculate velocity?
Here we have given that the distance = 3/4 of mile = 3/4 x 1 = 3/4 mile
Also we have given time = 1/10 of the hour = 1/10 hr.
Now substitute these values into above formula
Velocity = \(\frac{3/4}{1/10} =\frac{30}{4} =7.5\)
Therefore the required rate in mile per hour = 7.5 miles per hr.
This is the final answer.
