Two canoes travel down a river, starting at 9:00 a.M. One canoe travels twice as fast as the other. After 4.5 hours, the canoes
Vedmedyk [2.9K]

Answer:

v_1=3.33 \ miles/hour\\v_2=6.66 \ miles/hour

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

\displaystyle v=\frac{x}{t}

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

v_2=2v_1

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

x_1=v_1t

x_2=v_2t

Since

v_2=2v_1

Then

x_2=2v_1t

The distance between them is

X=x_2-x_1=2v_1t-v_1t

X=v_1t

That distance is known and equals 11.25 miles, thus

v_1t=15

Solving for v1 and using t=4.5 hours

\displaystyle v_1=\frac{15}{4.5}

v_1=3.33 \ miles/hour

v_2=2\times 3.33

\boxed{v_2=6.66 \ miles/hour}
