Sagot :
Answer:
7
Step-by-step explanation:
Let's call x the amount of miles that equal a lap.
So on Monday Wednesday and Friday, she runs 4x + 6 miles.
On Tuesday and Sunday she runs 6x + 2 miles.
And the problem says that she runs the same distance every day, so that means that
4x + 6 = 6x + 2
Now we solve that equation:
4x + 6 = 6x + 2
6 = 6x + 2 - 4x
6 - 2 = 6x - 4x
4 = 2x
x = 2
After that we choose either 4x + 6 or 6x + 2 to calculate the distance she runs on per day by replacing the x with a 2.
4(2) + 6 = 14
6(2) + 2 = 14
Finally we just divide the amount of miles (14) by the amount of miles per lap (2).
14/2 = 7 laps
