It is the first answer, x=4; y=8
Set up and add equations:
4x+y=24
+ x-y=-4
So 5x=20 (the y’s cancel)
X=4
Then substitute in 4(4)+y=24
16+y=24
Y=8
Answer:
19.8 minutes
Step-by-step explanation:
Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes
total time = 10 minutes + 9.8 minutes = 19.8 minutes
