Q2. - Precalculus Enhanced with Graphing Utilities

Question

If a particle has a speed of r feet per second and travels a distance d (in feet) in time t (in seconds), then $d=\_\_\_\_$.

Step-by-Step Solution

Answer

The solution is  $\left(r,t\right)$.

Step 1. Given information

A particle has a speed of r feet per second and travels a distance d (in feet) in time t (in seconds).

Step 2. Calculation.

Speed tells us how fast something or someone is traveling, distance refers to the numerical measurement of how far an object is from a particular place and time refers to an interval separating two events.

The formula  $\mathrm{speed}=\frac{\mathrm{distance}}{\mathrm{time}}$can be rearranged for distance as $\mathrm{distance}=\mathrm{speed}\times \mathrm{time}$.

The speed of a particle is r feet per second and travels a distance d (in feet) in time t (in seconds), then,

$d=r·t$
