Lesson 5.3: Rational 2.
Jill is filling a water trough for her horse. Using pump A, the trough is filled up in half an
hour. Using pump B, the trough is filled up in three quarters of an hour. How long does it
take to fill the trough using both pumps?

It will take 18 minutes to fill the trough using both pumps.

Step-by-step explanation:

Given that:

Time taken by pump A = half hour = 30 minutes

Time taken by pump B = three quarters of an hour

One quarter =

One hour = 60 minutes

Three quarters of an hour = = 45 minutes

Let,

x be the time taken by both pumps to fill the trough.

Hence,

It will take 18 minutes to fill the trough using both pumps.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
