A train starting from rest first accelerates uniformly up to a speed of 80 km/h for time \(t\), then it moves with a constant speed for time \(3 t\). The average speed of the train for this duration of journey will be (in k m/h ) : 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
