Question

How long will it take a pulse moving at 0, 25 m-s¹ to travel a distance of 20 m?​

Answer 1

T=80

Step-by-step explanation:

soln

v=0.25ms

d=20m

t=?

therefore; velocity=distance/time taken

equating the valuables we have

0.25=20/t

making t the subject formula we have

t=20/0.25 => 80s
