Roberto and his dad drove the long way from town a to town b, ate lunch and then took the straight short cut back home. what was their displacement after making the trip?
a) 20 km
b) 50 km
c) 70 km
d) 0 km

The answer is 0.

Step-by-step explanation:

Roberto and his dad returns back exactly the same spot after the long trip to town B and short trip from town B. Despite, they made 70km road while travelling, they exactly didn't made any displacement at the end of the trip. Because, they are exactly at the same spot that they started.

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
