Answer 1

Answer:

A partical travel 1st half distance with uniform speed of 40m/s and next half distance with uniform speed of 80m/s calculate average speed

Answer 2

Answer:

Let total distance be 2D . Given, D = 30t1 = 60t2 or, t1 = D30, t2 = D60 Thus, average speed = 2Dt1+t2 = 2D D30+ D60 = 40 m/s
