What is 420 ft painted in 36 min f ft painted in 30 min?

To find the rate of painting, divide the total feet painted by the time taken. For 420 feet in 36 minutes, the rate is 420 ft / 36 min = 11.67 ft/min. For f feet painted in 30 minutes, the rate would be f / 30 min. To compare the two, you can express f in terms of the same rate: if f = 11.67 ft/min × 30 min, then f = 350 ft.
