Question

What is Marie's instantaneous speed at 20 minutes in miles/min?

Answer 1

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  = $\frac{distance}{time}$

At 20min the distance covered is 5miles;

    Instantaneous speed  = $\frac{5 miles }{20mins}$   = 0.25miles/min
