Answer:
0.25miles/min
Explanation:
Instantaneous speed of a person or an object is its speed at a particular moment usually at a period of time.
The speedometer of a car reports the instantaneous speed.
It can be mathematically expressed as;
Instantaneous speed = [tex]\frac{distance}{time}[/tex]
At 20min the distance covered is 5miles;
Instantaneous speed = [tex]\frac{5 miles }{20mins}[/tex] = 0.25miles/min
