Answer:
The correct option is d.
Step-by-step explanation:
The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations
Car A:
... (1)
Car B:
.... (2)
Equate equation (1) and (2), to find the hours after which the two cars be at the same distance from their starting point.




The value of x is 3. It means after 3 hours two cars be at the same distance from their starting point.
Substitute x=3 in equation (1) to find the distance.


The distance is 190 miles.
Therefore option d is correct.
