Question

julissa works in the warehouse of a large online retailer. on tuesday from 9:00 a.m. to 3:00 p.m., she found that she had walked 20,458 steps preparing orders to be shipped. approximately how many steps did she walk each hour?

3,409.6 steps
3,409.\bar{6} steps
4,091.6 steps
4,091.\bar{6} steps

Explanation:

Calculate elapsed time

Using the Time Conversion knowledge point

$$ \text{9:00 a.m. to 12:00 p.m. (noon)} = 3\text{ hours} $$

$$ \text{12:00 p.m. to 3:00 p.m.} = 3\text{ hours} $$

$$ \text{Total Time} = 3 + 3 = 6\text{ hours} $$

Divide total steps by total hours

Using the Long Division Steps knowledge point

$$ \text{Steps per hour} = \frac{20,458}{6} $$

$$ 20,458 \div 6 = 3,409.6666\dots $$

Represent as a repeating decimal

Using the Repeating Decimals knowledge point

$$ 3,409.6666\dots = 3,409.\bar{6} $$

Answer:

• 3,409.6 steps
• 3,409.\bar{6} steps (Correct answer)
• 4,091.6 steps
• 4,091.\bar{6} steps
