Question:

A woman walks briskly at 2.00 m/s. How much time will it take her to walk one mile? (Answer in minutes)

Velocity:

The velocity of an object is defined as the rate of change of its displacement.

{eq}v = \dfrac{dx}{dt} {/eq}

The speed is the ratio of the distance traveled and the time taken.

Answer and Explanation:

Given:

{eq}v = 2\ m/s\\ d = 1 \ mile = 1609.34\ m {/eq}

By the formula of the velocity,

{eq}v = \dfrac{d}{t}\\ 2 = \dfrac{1609.34}{t}\\ t = 804.67\ s\\ t = 13.4\ min\\ {/eq}
