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

The solution is $\left(r·t\right).$

See the step by step solution

## 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 travelling, 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 $speed=\frac{dis\mathrm{tan}ce}{time}$ can be rearranged for distance as $dis\mathrm{tan}ce=speed×time$.

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

$d=r·t$
