Final answer:
Katie will travel a distance of 1092 m.
Step-by-step explanation:
To calculate the distance Katie will travel, we can use the formula distance = velocity x time. Megan is pushing the wagon at a constant velocity of 7 m/s for 156 seconds. So the distance Katie will travel is 7 m/s x 156 s = 1092 m. Therefore, the correct answer is option A) 1092 m.
