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 r·t.

See the step by step solution

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=distancetime can be rearranged for distance as distance=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
