Answer:
The answer is 70 km
Explanation:
Firstly, there are few facts that we have to know:
- The car travels northward and then eastward
, so both direction are perpendicular.
- It doesn't matter the total time, because we already know the total distance in every direction.
- The question is about distance, NOT displacement. I have attached an image that shows the difference between both concepts.
Finally, the first 25 min the car traveled in total 30 km and after that, the car traveled in total 40 km during 35 min. So, the total distance is:
30+40=70 km.
