To find the missing values in the table, we can use the conversion factor between kilometers and miles. The approximate conversion factor is:
1 kilometer ≈ 0.621371 miles.
Now, we can fill in the missing values using this factor.
For 20 kilometers: \[ 20 \text{ km} \times 0.621371 \text{ miles/km} \approx 12.4274 \text{ miles} \] So, 20 kilometers is approximately 12.4 miles.
For 30 kilometers: \[ 30 \text{ km} \times 0.621371 \text{ miles/km} \approx 18.6411 \text{ miles} \] So, 30 kilometers is approximately 18.6 miles.
Now, here is the completed table:
Kilometers | Miles --- | --- 2 | 1.2 7 | 4.2 20 | 12.4 30 | 18.6
