Answer:
It will take a total of 2.73 hours if they worked together
Step-by-step explanation:
Here, we are seeking to calculate the joint rate.
Let the amount of work to be done is say x
Seth’s rate will be x/6 , while violet’s rate will be x/5
Their joint rate will be ;
x/6 + x/5 = 11x/30
The time it will take them to build the house together will be equal to the amount of work divided by the joint rate.
That will be x divided by 11x/30
= x * 30/11x
= 30/11 hours which is Approximately 2.73 hours
Ok
6+1=7
if only we could find 1
hmm
4+1=5
so mark a starting line
put the 4 inch and 5 inch wood at that line, facing the same direction (lying flat on paper)
the difference between the pieces of wood is 1 inch
mark the end of the 5 inch and the end of the 4 inch
that is 1 inch
now pick either end of that 1 inch mark and measure 6 inches more
The answer is .....................1600......
