Question

State whether the conclusion drawn from the given statement is True or False.

Given: The ship's average speed over the $9$ kilometers was less than $60$ meters per minute.

Did it take a certain ship less than $3$ hours to travel $9$ kilometers? $(1kilometer=1,000meters)$

• A. True
• B. False

Answer 1

The correct option is B False

$9$ kilometers in $3$ hours. Create an RTD chart, and convert kilometers to meters and hours to minutes:

$180r=9,000$

$r=50$

The question asks whether the ship traveled $9$ kilometers in less than $3$ hours. The ship must travel faster than $50$ meters/min to make it in less than $3$ hours. Therefore, the question is really asking, is $r>50$?

If the average speed of the ship was less than $60$ meters per minute, then $r<60$. This is not enough information to guarantee that $r>50$.
