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$d=\_\_\_\_\_\_\_$.

Short answer

The solution is $\left(r·t\right).$

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 $speed=\frac{dis\tan ce}{time}$can be rearranged for distance as$dis\tan ce=speed\times time$.

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

$d=r·t$
