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
