Answer:

0.56 m/s

Step-by-step explanation:

The average speed of a body tells how fast is the body moving; it is calculated as:

v=\frac{d}{t}

where

d is the distance covered

t is the time elapsed

In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:

d = 1 km = 1000 m

The time elapsed to cover this distance is:

t=30 min \cdot 60 =1800 s

Therefore, Ben's average speed is:

v=\frac{1000}{1800}=0.56 m/s
