एक वस्तु 2.6 मिनट में 15 मीटर की दूरी तय करती है और अगले 26 किमी की दूरी 30 किमी/घंटा की गति से तय करती है। पूरी यात्रा के लिए इसकी औसत गति (मीटर/सेकंड में) ज्ञात कीजिए।

If a person travels a distance of 90 km at a speed of 45 km/h and another distance of 150 km at a speed of 50 km/h, what is his average speed for the entire journey?

Anita travels from place A to place B at a speed of 30 km/h, from place B to place C at 40 km/h, and from place C to place D at 120 km/h. If the distances between these places are equal, what is Anita's average speed (in km/h) during the entire journey?
