A person can paint a 2.5ft
2
of a wall in 5 minutes. How much ft
2
of the wall will he paint in 6 hours?

First, let's find the rate of painting per minute:
Rate=
5minutes
2.5ft
2

​
=0.5ft
2
/minute
Next, let's convert the total time from hours to minutes:

6hours=6×60=360minutes
Now, calculate the area painted in 360 minutes:

Area=Rate×Time=0.5ft
2
/minute×360minutes=180ft
2

Therefore, he will paint 180ft
2
of the wall in 6 hours.
