Question

complete each table and write a unit rate for the given situation. 1. general house cleaning (sweeping the floors, vacuuming, laundry, etc.) can burn 470 calories every 2 hours. \

$$\begin{tabular}{|l|c|c|c|c|c|} \\hline time (hours) & 1 & 2 & 3 & 4 & 5 \\\\ \\hline calories burned & & & & & \\\\ \\hline \\end{tabular}$$

Explanation:

Step1: Find unit rate (calories per hour)

To find the calories burned per hour, we divide the total calories burned in 2 hours by 2. So, the unit rate $r = \frac{470}{2}= 235$ calories per hour.

Step2: Calculate calories for 1 hour

Using the unit rate, for 1 hour, calories burned = $235\times1 = 235$.

Step3: Calculate calories for 3 hours

For 3 hours, calories burned = $235\times3 = 705$.

Step4: Calculate calories for 4 hours

For 4 hours, calories burned = $235\times4 = 940$.

Step5: Calculate calories for 5 hours

For 5 hours, calories burned = $235\times5 = 1175$. Also, we know for 2 hours it's 470 (given).

Answer:

The completed table is:

Time (hours)	1	2	3	4	5

The unit rate is 235 calories per hour.
