Jacob spends 60 minutes in the gym every day doing freehand exercises and running on the treadmill. He spends 30 minutes more running on the treadmill than doing freehand exercises.

Part B: How much time does Jacob spend on doing freehand exercises? (3 points)

Part C: Is it possible for Jacob to have spent 40 minutes running on the treadmill? Explain your reasoning. (2 points)

Answer 2

Part A:

x+y=60
x=30+y

Part B:

Y= free hand
X= treadmill

y+x=60
x=y+30

y+y+30=60
2y=60-30
2y=30
y=15

free hand = 15 minutes
x+y=60
x+15=60
x=60-15
x=45

Part C:

Yes he could of done 40 minutes on the treadmill because the equation said he was in the gym for a total amount of 55 minutes. (15+40)
