Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.

lol that just means free points for me. ;)
Answer:
18 or 17
Step-by-step explanation:
Plan a= 2x + 10
plan b= .25x + 40
2x + 10 = .25 + 40
1.75x=30
x=17.14
The dozen is 36...36/8= 4.5. So 1.5x4.5=6.75 which converts to 6 3/4 teaspoons
1°C is the temperature at noon.
