$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.

Area = 270 square feet, length = 18 feet

270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet

The room is 15 feet wide.

An ice cream machine produced 52 ice creams per minute. After reconditioning, its speed increased to 65 ice creams per minute. B

Anastasy [175]

Answer:25 %

Step-by-step explanation:

Given

Earlier machine was producing 52 ice cream per minute and

Now it is Producing 65 ice creams per minute

So percentage increase of the machine $=\frac{\text{final-Initial}}{\text{Initial}}\times 100$

$=\frac{65-52}{52}\times 100$

$=\frac{13}{52}\times 100$

$=\frac{1}{4}\times 100=25\ \%$

So there is increase of 25 % in speed
