Answer:

180 km

Step-by-step explanation:

Considering the car has been moving with a constant speed of 60 km/hr for 3 hours then the car has moved 60*3 = 180km

and per hour would be 60 so she's traveled 180 km

You would add the additional distance travelled to the 160 already travelled to find d.
The additional distance is 3 x 60 = 180 and then you add the 180 to the 160 for a total d of 340.
