type the correct answer in the box. use numbers instead of words. carla mows grass at a rate of 90 square yards of area per 10 minutes. to the nearest whole number, what is the equivalent rate in square meters per hour? use 1 square meter ≈ 1.2 square yards and 1 hour = 60 minutes. square meters per hour

Answer

Explanation:

Step1: Find the rate in square yards per hour

First, we know that Carla mows 90 square yards in 10 minutes. To find the rate per hour, we need to convert minutes to hours. Since 1 hour = 60 minutes, we can find out how many 10 - minute intervals are in an hour: $\frac{60}{10}=6$. Then, the area mowed per hour in square yards is $90\times6 = 540$ square yards per hour.

Step2: Convert square yards to square meters

We know that 1 square meter $\approx$ 1.2 square yards. So to convert square yards to square meters, we divide the number of square yards by 1.2. Let $x$ be the area in square meters per hour. Then $x=\frac{540}{1.2}$. Calculating this, $540\div1.2 = 450$.

Answer:

450
