Question

A boat moves 60 kilometers east from point A to point B. There, it reverses direction and travels another 45 kilometers toward point A. What are the total distance and total displacement of the boat?

Answer 1

Answer:

Total distance: 105km, Total (Final) displacement: 15km towards point A (west)

Explanation:

Total distance= Length of actual path covered= 60km+45km= 105km

Displacement= Final distance between initial and final point= 60km-45km= 15km (towards west)

Hope this helps! :D

Answer 2

Answer:

30

Explanation:

The boat travels from point A to point B which takes 60 then reverse back 45 which means 60-45 = 15 then continue in the same direction for 45 km but from that point 15 km already left from that point to A so the displacement is 45-15=30
