A larger impulse. A 1-kg ball has twice as much speed as a 10-kg ball.
Explanation:
The rule to get the average speed is as follows:

We are given that:
distance = 250 m
time = 110 sec
Substitute with the givens in the above equation to get the average speed as follows:
average speed = 250/110 = 25/11 meters/sec
