A truck driver attempting to deliver some
furniture travels 5 km east, turns around and
travels 5 km west, and then travels 12 km east
to his destination.
What distance has the driver traveled?
distance? add them: 5+5+12 km
displacement? 12kmE
To calculate the total distance traveled by the truck driver, we need to add up the distances traveled in each step.
Step 1: The driver travels 5 km east.
Distance traveled = 5 km
Step 2: The driver turns around and travels 5 km west.
Distance traveled = 5 km + 5 km = 10 km
Step 3: The driver travels 12 km east to the destination.
Distance traveled = 10 km + 12 km = 22 km
Therefore, the driver has traveled a total distance of 22 km.
To find the total distance the driver has traveled, we need to add up the distances of each individual leg of the journey.
First, the driver travels 5 km east. This adds 5 km to the total distance.
Next, the driver turns around and travels 5 km west. This cancels out the previous 5 km east, so it doesn't change the total distance.
Finally, the driver travels 12 km east to reach the destination. This adds 12 km to the total distance.
Adding up these distances, we have:
5 km (east) + 0 km (west) + 12 km (east) = 17 km
Therefore, the driver has traveled a total distance of 17 km.
