Question
x + = 75 y
The equation above relates the number of minutes, x, Maria spends running each day and the number of minutes, y, she spends biking each day. In the equation, what does the number 75 represent?
- The number of minutes spent running each day
- The number of minutes spent biking each day
- The total number of minutes spent running and biking each day
- The number of minutes spent biking for each minute spent running
The correct answer is: The total number of minutes spent running and biking each day
HINT – Time given to both the activities is added
SOLUTION – Time spends running each day = x min
Time spends biking each day = y min
Now, it is given that x + y = 75
i.e. 75 represent total number of minutes spend running and biking each day.
So, option C is correct
