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.

Step-by-step explanation:
Answer:29
Step-by-step explanation: the answer is 29 because if there are three consecutive numbers, we know that the second and third number must be one and two units larger respectively. As such you can subtract the difference from the combined number (1 (2nd number) + 2 (third number) = 3 --> 90 - 3 = 87). So, if you divide the new number (87) by three (the number of consecutive integers required for this question) the answer is 29. If the answer is 29, we know that the second and third number in the sequence must be 30 and 31. 29 + 30 + 31 = 90.
2x+10=0
subtract 10 from both sides
2x=(-10)
divide 2 from both sides
x=-5
The ranges is 27
Hope that helps!
