Chanice drives her scooter 7 kilometers north she stops for lunch and then drives 5 kilometers east what distance did she cover?
? What was her displacement
2 answers:
Answer:
Total distance of covered by Chanice is 12 km
8.60 km was her displacement in the direction of north-east.
Explanation:
Distance covered by Chanice in north direction = 7 km
Distance covered by Chanice in an east direction = 5 km
Total distance of covered by Chanice = 7 km+ 5 km = 12 km
Displacement is defined as shortest distance from initial point to final point.
In a ΔABC, the displacement of the Chanice = AC
ΔABC, is a right angled triangle.So, by applying Pythagoras theorem we can determine the the length of AC.
AC = 8.60 km
8.60 km was her displacement in the direction of north-east.
