Answer:
445.5 minutes
or 7 hours 25 minutes 30 seconds
Step-by-step explanation:
We can use ratio's to solve
50 ft^2 495 ft^2
-------------- = ------------
45 minutes x minutes
Using cross products
50x = 45*495
50x=22275
Divide each side by 50
50x/50 = 22275/50
x =445.5
445.5 minutes
If we want to convert to hours and minutes, divide by 60
7 hours is 420 minutes
445.5 -420 = 25.5
7 hours 25 minutes
.5 minutes is 30 seconds
7 hours 25 minutes 30 seconds
