Step-by-step explanation:
<u>Constant Speed Motion
</u>
When the object travels the same distances in the same period of time, the speed is constant and is can be calculated as

where x is the distance and t is the time
There are two canoes traveling at speeds v1 and v2. One of them has twice the speed as the other. Let's say

When t hours have passed, the canoes have traveled x1 and x2 respectively.


Since

Then

The distance between them is


That distance is known and equals 11.25 miles, thus

Solving for v1 and using t=4.5 hours
