if an area can be washed at a rate of 4,900 cm2/ minute, how many square inches can be washed per hour?

Answer : 4.5 × 10⁴ square inches can be washed per hour.

Step-by-step explanation :

As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.

Given conversions are:

1 cm = 0.39 in    and    1 hr = 60 min

As, 1 cm² = (0.39)² in²    and    1 min = 1/60 hr

So,

Now we have to determine the square inches can be washed per hour.

As,

So,

Therefore, 4.5 × 10⁴ square inches can be washed per hour.
