Step-by-step explanation:

Given : Superman needs to save Lois from the clutches of Lex Luthor. After flying for 7 seconds, he is 1687 meters from her. Then at 15 seconds, he is 1215 meters from her.

To Find :

What is Superman's average rate?  

How far does Superman fly every 14 seconds?

How close to Lois is Superman after 29 seconds?

Solution :

seconds             meters

 7                          1687

15                         1215

Slope tells about the rate

Thus slope =

              =

             = -59

Thus  Superman's average rate is -59m/s

Every second he's 59 meters closer to Lois,

So if at 15 seconds he's 1215 meters, then the second before that he was 1215-(-59)=1215+59 =1274 meters closer.

how close is he at 29 seconds?

Since the 29 second is 14 seconds away from the 15 seconds, So, 1215 + 14(-29)

= 809 meters
