Andrew [12]

Answer:

2\text{ mph}

Step-by-step explanation:

GIVEN: kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling against the current. he paddles 6 mph with no current.

TO FIND: what was the speed of the current.

SOLUTION:

distance of island from the shore =8 miles

total time taken by Kayden =2 hours

speed of Kayden in still water =6\text{ mph}

Let the speed of current be x

Speed of Kayden against current =6-x\text{ mph}

As,

\text{Time}=\frac{\text{Distance}}{\text{speed}}

2=\frac{8}{6-x}

12-2x=8

x=2\text{ mph}

Hence speed of current is 2\text{ mph}
