3 hours is 1 hour longer than 175 minutes because 175 minutes is only 2 hours and 55 minutes so 3 hours is 5 minutes longer than 175 minutes
To mix cleaner and water you need to divide the bucket's capacity into 4.It's easy in this case as gallon is divided into quarts (1 gallon = 4 quarts).We know that one part will be cleaner, it means that you will need to use 1 quart of the cleaner.

Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
