15.00 m/s because it’s at half the speed imagine them both going for 1 second

Answer:

15 m/s

Explanation:

Let in time t the object moves a distance d with speed 30 m/s.

Again in time t, it covers half of distance and the new speed is v.

So, d = 30 x t ..... (1)

d/2 = v x t

Put d = 30 t from equation (1)

30 x t / 2 = v x t

v = 15 m/s
