On the River current a canoe traveled 30 km in 3 hours and 20 min, against the current the canoe traveled 28 km in 4 hours. how
mihalych1998 [28]

Answer:

12 km

Step-by-step explanation:

Let

x km/h = speed of the canoe on the lake

y km/h = speed of the current

<u>With the current:</u>

Speed = x + y km/h

Distance = 30 km

Time = 3 hours 20 minutes = 3\dfrac{1}{3} hours

Thus,

30=3\dfrac{1}{3}(x+y)\\ \\30=\dfrac{10}{3}(x+y)\\ \\90=10(x+y)\\ \\x+y=9

<u>Against the current:</u>

Speed = x - y km/h

Distance = 28 km

Time = 4 hours

Thus,

28=4(x-y)\\ \\x-y=7

Add these two equations:

x+y+x-y=9+7\\ \\2x=16\\ \\x=8\ km/h

<u>On the lake:</u>

Time = 1.5 hours

Speed = 8 km/h

Distance =8\cdot 1.5=12\ km

The number is 23.

Step-by-step explanation:

5n + 7 = 122               Subtract 7 on both sides

     5n = 115                 Isolate the variable by dividing 5 on both sides

        n = 23
