From the uploaded image, I can help analyze the problem step by step:

(a) Matching Time and Distance:

The task involves calculating and matching the correct time and distance based on given speed and time values.

Given:

1. Speed 1: 160 km/h, Distance = 120 km

   • $\text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{120}{160}$
   • $\text{Time} = 0.75$ hours $= 45 \text{ minutes}$.

2. Speed 2: 85 km/h, Time = 1.5 hours

   • $\text{Distance} = \text{Speed} \times \text{Time} = 85 \times 1.5 = 127.5 \, \text{km}$.

Thus, the correct matching pairs:

• 45 minutes for 120 km.
• 127.5 km for 1.5 hours.

(b) Correct Unit Conversion:

(i) $0.35 \, l/km = 350 \, ml/km$ ✔️ Correct

• $1 \, l = 1000 \, ml$, so $0.35 \times 1000 = 350 \, ml$.

Let me know if you need further explanation or if you'd like to analyze another problem.
