375km
Explanation:
Given parameters:
Time of travel = 5hr
Average velocity = 75km/hr south
Unknown:
Displacement between Chihuahua and El paso = ?
Solution:
Velocity is the rate of change of displacement of a body with time. It is a vector quantity that has both magnitude and direction;
Velocity =
Since the unknown is displacement;
displacement = velocity x time
input the values;
displacement = 75km/hr x 5hr = 375km

The expression for the frictional force between the sled and the ground is:
where
is the coefficient of friction, m is the mass of the object and 
is the gravitational acceleration.
The friction force in our problem is F=80.85 N. The mass of the object is m=15 kg. Re-arranging the formula, we can find the value of k:
