A steamboat tour makes a trip upstream 24 miles and back in total of 10 hours in a river with a current speed of 1mph. What is the speed of the steamboat in still water

Sagot :

Answer:

Going upstream, Distance = (Rate)(Time), so 16 = (B-C)(2)

Going downstream, Distance = (Rate)(Time), so 36 = (B+C)(3)

Now we'll solve the system of equations:

16 = 2(B-C)

36 = 3(B+C)

If we divide both sides of the first equation by 2, it will become 8 = B-C.

If we divide both sides of the second equation by 3, it will become 12 = B+C.

We'll add these equations together to find our solution:

8  =  B-C

12 = B+C

20 = 2B

10 = B

Step-by-step explanation:

Answer:

The speed of the current is 2 miles per hour.
