Show answer & explanation
Correct answer: A
Key idea: the racehorse covers the same distance in 3 hours that the pony covered in the pony's total running time (pony ran 2 hours before the chase plus the 3-hour chase).
Distance covered by the racehorse during the chase = 49 km/h × 3 h = 147 km.
Total time the pony ran = 2 h (head start) + 3 h (during chase) = 5 h.
Pony's average speed = distance ÷ time = 147 km ÷ 5 h = 29.4 km/h.
Answer: 29.4 km/h
