First, you must convert 7.68cal/sec to cal/min. To do so, multiply 7.68x60(seconds, thus making a minute). 7.68x60=460.8 

Next, we must convert 460.8 cal to kcal. To do so, divide 460.8 by 1000 (460.8/1000). The result is .4608 kcal/min

Answer:

7.68 cal/sec = 0.461 kcal/min

Explanation:

Measurement = 7.68 cal/sec

Unit conversions:

1 cal (calorie) = 10⁻³ kcal (kilocalories)

1 min = 60 sec

Step 1: convert cal to kcal

[tex]7.68 cal/sec= \frac{7.68\ cal * 10^{-3} kcal}{1\ cal} *\frac{1}{sec} = 7.68*10^{-3} kcal/sec[/tex]

Step 2: convert sec to min

[tex]7.68*10^{-3} kcal/sec=\frac{7.68*10^{-3} kcal}{sec} *\frac{60\ sec}{1\ min} = 0.461 kcal/min[/tex]
