Given,
On a fishing trip;
Justin rides in a boat 12 km south, then 4 km west, and finally, 1 km north.
To find,
a) Total distance covered
b) Total displacement
Solution,
We can simply solve this numerical problem by using the following process:
According to the question;
Total distance covered
= 12 km south + 4 km west + 1 km north
= 17 Km
And, total displacement
= √{(12-1)^2 + (4)^2}
(Using Pythagoras theorem)
= √{(11)^2 + (4)^2}
= √{121 + 16}
= √137
= 11.7 Km approximately
Hence, the total distance traveled by Justin is 17 kilometers and his total displacement is approximately equal to 11.7 kilometers.
