Awesome! If you have travelled $$5 \, \mathrm{miles}$$ in one direction, and travelled back $$3 \, \mathrm{miles}$$, you are only $$2 \, \mathrm{miles}$$ from where you started.
What about the net displacement and the total distance travelled in this scenario: you ride your bike $$7 \, \mathrm{miles}$$ towards the East. You stop for half an hour. Then, you continue going along the East for $$5 \, \mathrm{miles}$$?
• Final displacement $$= \, 12 \, \mathrm{miles}$$; Total distance $$= \, 12 \, \mathrm{miles}$$
• Final displacement $$= \, 7 \, \mathrm{miles}$$; Total distance $$= \, 7 \, \mathrm{miles}$$
• Final displacement $$= \, 2 \, \mathrm{miles}$$; Total distance $$= \, 12 \, \mathrm{miles}$$
• Final displacement $$= \, 12 \, \mathrm{miles}$$; Total distance $$= \, 2 \, \mathrm{miles}$$
