A bullet train covers a fixed distance in 30 minutes at an average speed of 240 km/h. Due to track maintenance, it needs to be diverted, increasing the distance by 20%. If the train needs to arrive at its destination on time (i.e., in 30 minutes), what should its new average speed be in km/h? एक बुलेट ट्रेन 240 किमी/घंटा की औसत गति से एक निश्चित दूरी 30 मिनट में तय करती है। ट्रैक के रखरखाव के कारण ट्रेन का मार्ग बदलना पड़ता है, जिससे दूरी 20% बढ़ जाती है। यदि ट्रेन को समय पर अर्थात 30 मिनट में ही गंतव्य तक पहुँचना है, तो उसकी नई औसत गति कितनी होनी चाहिए?
Since the travel time remains constant at 30 minutes, speed is directly proportional to distance. चूँकि यात्रा का समय 30 मिनट ही रहता है, इसलिए ग…

Analysts should distinguish such changes in product mix from improvements in the efficiency of producing each product. Options:
