2. Distance ridden on Tuesday:

   • He rode 20% farther than on Monday.
   • To find 20% of 8 kilometers: \[ 20% , of , 8 = 0.20 \times 8 = 1.6 , kilometers \]
   • Therefore, the distance he rode on Tuesday is: \[ 8 + 1.6 = 9.6 , kilometers \]

3. How many more kilometers did Luca ride his bicycle on Tuesday? \[ 9.6 - 8 = 1.6 , kilometers \]

4. Distance ridden on Wednesday:

   • He rode 10% farther than on Tuesday.
   • To find 10% of 9.6 kilometers: \[ 10% , of , 9.6 = 0.10 \times 9.6 = 0.96 , kilometers \]
   • Therefore, the distance he rode on Wednesday is: \[ 9.6 + 0.96 = 10.56 , kilometers \]

5. How many more kilometers did Luca ride his bicycle on Wednesday? \[ 10.56 - 9.6 = 0.96 , kilometers \]
