Question

If an area can be washed at a rate of 3,600 cm2/minute, how many square inches can be washed per hour? Enter your answer with the correct number of significant digits. Use the equivalent measures indicated. (1 centimeter ≈ 0.39 inch, 1 hour = 60 minutes)

Answer 1

To convert the rate of washing from square centimeters per minute to square inches per hour, multiply the given rate by the appropriate conversion factors.

Step-by-step explanation:

To convert the area from square centimeters to square inches, we need to use the conversion factor of 0.155 square inches per square centimeter. First, we need to convert the rate from square centimeters per minute to square inches per minute by multiplying by the conversion factor. Next, we can convert the rate from minutes to hours by multiplying by 60. Finally, we multiply the rate in square inches per minute by the number of minutes in an hour to find the rate in square inches per hour. The final answer will have the correct number of significant digits, which is determined by the given conversion factors and the original question.
