In the given question, there are certain known facts. the thing that need to be deduced is the amount of wall that can be painted in 1 minute. it is given that 7/8 of the wall can be painted in 11/6 hours.
Firstly let us convert the 11/6 hours into minutes. For converting this we need to multiply 11/6 with 60
So
11/6 hours = (11/6 * 60) minutes
= 110 minutes
now it is known that 7/8 of the wall can be painted in 110 minutes. We have to find out the amount of wall painted in 1 minute
So
110 minutes = 7/8
1 minute = (7/8)/110
= .00795
So .00795 is the amount of wall that will be painted.
