The answer is C because : total time = 14min; Total distance = 50km, 14 min in hours is equal to 14/60 = 0.23hrs if you divide, then speed is equal to 50km/0.23hrs = 50x100/23 = 5000/23 = 214.28km/hr. You're welcome.

I think that SOF must give a proper solution to this answer. Average speed=Total Distance/Total Time. Here, total distance = 50 km and the total time= 35 mins. Therefore, average speed= 50/35=10/7=1.42....km/min. I request SOF to kindly tell the solution.
