I have to displacement problems that i can't get right.
While John is traveling along a straight interstate highway, he notices that the mile marker reads 233. John travels until he reaches the 155-mile marker and then retraces his path to the 172-mile marker. What is John's resultant displacement from the 233-mile marker?
I thought the answer for this one would be 61 but it is marked wrong.
Bob walks 57 m and then he walks 125 m. What is Bob's displacement if he walks east then west?
I thought the answer for this one would be 68 but it is marked wrong.
