Answer:
The amount of calories Lucie will burn by jumping for 1 minute is 8 calories
Step-by-step explanation:
The given data values are;
Minutes [tex]{}[/tex] Calories Burned
40 [tex]{}[/tex] 320
80 [tex]{}[/tex] 640
120 [tex]{}[/tex] 960
160 [tex]{}[/tex] 1280
The value of calories burnt and the number of minutes of jump robe are seen to be directly proportional, such that we have;
40 minutes of jump rope will yield 320 calories burnt
Therefore we have;
1 minute of jump rope will yield 320/40 = 8 calories burnt
The amount of calories Lucie will burn by jumping for 1 minute = 8 calories.
