Accepted Answer
The car's average speed is 97 km/hr.Then for calculation purposes, we can assume that it covers 97 km in the first hour, 97 km in the second hour, 97 km in the third hour, and 97 km in the fourth hour.All together, the car covers (97 x 4) = 388 km of distance.We don't know the car's velocity, because we have no information about the direction it moved at any time during the four hours. So we have no way tocalculate how far it was from the starting point at the end of the fourth hour.For all we can tell, if the direction (and therefore the velocity) varied just right,the car could have ended up exactly where it started.
Suggested Answer
i think the answer is 388 because i multiplyed 97 by 4
