Question

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

Answer 1

0.25miles/min

Step-by-step 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 =
`(distance)/(time)`

At 20min the distance covered is 5miles;

Instantaneous speed =
`(5 miles )/(20mins)` = 0.25miles/min
