The average speed of the car for the given distance and time is 60 mph.
The given parameters;
- time of motion of the car, t = 1.75 h
- initial position, x₁ = 10 miles
- final position, x₂ = 115 miles
The average speed of the car is determined by dividing the total distance by total time of motion as shown below;
[tex]average \ speed = \frac{total \ distance}{total \ time} \\\\average \ speed = \frac{115 - 10}{1.75} \\\\average \ speed = 60 \ mph[/tex]
Thus, the average speed of the car for the given distance and time is 60 mph.
