A Correct answer
Explanation

The correct answer is 'twenty kilometers and a half, one hour and a half' - this properly uses the pattern 'number + unit + and a half' for expressing 1.5 units. Both distance and time follow this construction: 'kilometers and a half' means 20.5 km, 'hour and a half' means 1.5 hours.
