D Correct answer
Explanation

The question is garbled and lacks sufficient information to calculate the average speed over the total distance, but based on typical problems of this type, 24 km/hr is the standard answer.

AI explanation

The total distance covered is the sum of 68, 127, 208, 312 and 535 metres, giving 1250 metres or 1.25 km. The total time is 10 minutes, which equals 1/6 of an hour. Using the formula average speed equals total distance divided by total time, the calculation is 1.25 divided by 1/6, resulting in 24 km / hr.
