To find out how many meters Isabella rides on Malcolm Drive, we first need to determine how much distance she has already covered on South Street and Oxford Avenue.
- Distance ridden on South Street: 430 meters
- Distance ridden on Oxford Avenue: 375 meters
Next, we calculate the total distance ridden on these two streets:
\[ \text{Total distance on South Street and Oxford Avenue} = 430 , \text{meters} + 375 , \text{meters} = 805 , \text{meters} \]
Now, we know that Isabella rides a total of 950 meters to work. To find out the distance she rides on Malcolm Drive, we subtract the distance she has already ridden from the total distance:
\[ \text{Distance on Malcolm Drive} = 950 , \text{meters} - 805 , \text{meters} = 145 , \text{meters} \]
Thus, Isabella rides 145 meters on Malcolm Drive.
