Question

Bob lives 2.8 miles from Sue and 1.6 miles from Cue. Write a double inequality to represent the possible distances d between Sue's home and Cue's home.

Answer 1

0 <= x <= 4.4

Explanation:

Let x be the distance between their homes.

using triangular inequality:

x <= (2.8 + 1.6) miles

0 <= x <= 4.4

Therefore, The double inequality to represent the possible distances d between Sue's home and Cue's home is 0 <= x <= 4.4
