Amie's father has asked him to paint the fence around their home. if the fence is 119.5 yards long, and jamie can paint an average of 4.78 yards of the fence per hour, how many hours will it take for jamie to finish painting the fence?

25 hrs... 119.5 divided by 4.78= 25

For this case we have the following formula by definition:
 t = d / v
 Where,
 d: distance
 v: speed
 t: time
 Substituting the values we have:
 t = 119.5 / 4.78
 t = 25 hours
  
 it will take for Jamie to finish painting the fence about 25 hours.
