Question

A particle travel 1st half distance with uniform speed of 40m/a and next half distance with uniform speed of 80m/s calculate average speed.​

Answer 1

Answer:

160/3 m/s = 53.33 m/s

Explanation:

Average speed = Total distance / Total time

Let total distance be x

Time taken to cover first half distance = (x/2) ÷ 40

Time taken to cover second half distance = (x/2) ÷ 80

Total time taken = x/80 + x/160 = 3x/160

Now, Average speed = x ÷ (3x/160)

Average speed = 160/3 = 53.33 m/s
