average speed = average distance / average time

distance = 1600 m

time = 200 sec

avg speed = 1600/200 = 8 m/s

Answer 2

We know,
Speed = distance / time

Given: d = 1600m
t = 3 min 20 sec = 60 X 3 + 20 = 200 sec
Now keeping value of distance and time in the formula:

Av. speed = 1600m/ 200sec
= 8m/s
