Answer:
6%
Step-by-step explanation:
You want the percentage increase from 158,800 to 168,328.
The percentage change is given by the formula ...
percentage change = ((new value)/(old value) -1) × 100%
For the given numbers, this is ...
(168328/158800 -1) × 100%
= (1.06 -1) × 100% = 6% . . . . increase
The annual distance driven increased by 6%.
