Question

the area of a rectangular region is increasing at a rate of 18,000 square centimeters per hour. what is this rate, in square meters per minute? (1meter=100centimeters)

Explanation:

Step1: Convert cm² to m²

Since 1m = 100cm, 1m² = (100cm)² = 10000cm². So 18000cm² = $\frac{18000}{10000}$m² = 1.8m².

Step2: Convert hours to minutes

1 hour = 60 minutes. So rate = $\frac{1.8m²}{60min}$ = 0.003 m²/min.

Answer:

0.003
