If the distance Tommy traveled remains constant and then increases it by 25%, what was the amount of time that passed must decrease by how much percent?

anonymous · Answer

amount of time that passed decreased by what percent

dan815 · Answer

okay let d be the distance tommy tavels
let t be the initial time
let v he the inital speed before 25% increase

v=d/t
t=d/v
now the speed got increase bt 25% so
new_v=1.25*v
         =5/4 v

new_t=d/1.25v
  =d/(5v/4)
  =4d/5v
  =4/5* d/v
so the new time is 4/5th of the old time
4/5 = 80%

so thats a 20% decrease
