Chapter 6: Q. 2 (page 364)

If a particle has a speed of rfeet per second and travels a distance d(in feet) in time t(in seconds), thend=_______.

Short Answer

Expert verified

The solution is r路t.

Step by step solution

01

Step 1. Given information 

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

02

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=distancetimecan be rearranged for distance asdistance=speed脳time.

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

d=r路t
