Acar travels 30 km north in 25 min. and 40 km east in 35 min. what is the total distance traveled

70 km

Explanation:

Before answering, let's remind the difference between distance and displacement:

- Distance: the total length of the path covered, no matter in which direction

- Displacement: the distance in a straigth line between the final point and the starting point of the motion

In this problem, we are asked to find the total distance travelled. So, we can simply add the length of the two parts of the path, regardless of their direction:

d = 30 km + 40 km = 70 km
