Question 252779
r * t = u


r  rate.
t = time
u = units


the unit is 1 bucket full of water.


the time is 5 minutes


the formula becomes:


r * 5 = 1


divide both sides of this equation by 5 to get:


r = 1/5


the bucket is being filled at the rate of 1/5 of the bucket per minute.


r * 1 = 1/5 * 1 = 1/5


in one minute, 1/5 of the bucket has been filled.
