Answer:
For the tiling Job; it takes the following for installing 100 tiles:
Dylan =2 hours
George = 4 hours
if they work together for the job, for 1 hour,
it would be the following no of tiles to be fixed:
Dylan + George = total tiles
100/2 + 100/4 = 50 + 25 = 75 tiles
If it takes George 1hr to fix 50 tiles,
For 30 minutes, Dylan will fix 25 tiles
Therefore Total tiles fixed = Dylan(1hr work) + George(1hr work) + Dylan (30mins work)
= 50 tiles + 25 tiles + 25 tiles = 100 tiles
Therefore, it will take approximately 1 hour for them to install 75 tiles in the low-income house for the families or
1.30 hours (1 hr, 30 minutes) to fix 100 tiles for the same low income families.
