A car travels north at 30 m/s for one half hour. It then travels south at 40 m/s for 15
minutes. The total distance the car has traveled and its displacement are?
The Attempt at a Solution
First of all i converted from m/s to km/h. I took the positive y-axis as the north direction and the negative y-axis as the south direction. I tried to find the distance using d= speed x time for both axis and summing them up but that seems to be so wrong and don't know what else to do...Any help will be very much appreciated thanks..
