Answer: Speed of motorboat= 25 km hr
Speed of current= 5km hr
Step-by-step explanation:
120/4= speed of motorboat with the current
120/6= speed of motorboat against the current
Get the average of those 2 numbers.
Motorboat=25 km hr
Speed of current= 5 km hr
Distribute 5 using the Distributive Property:
5(x+24)
Multiply 5 by x:
5x
Multiply 5 by 24:
120
Now, add the products:
5x+120 (Answer)
Hope it helps! Enjoy your day :)

Answer:
2+4
Answer: 12 days
Based on the question, we have to list the multiples of 3 and 4. This will be:
3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40.
The lowest common multiple is 12.
It will take 12 days before Korey runs and swims again on the same day.
Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
It is modeled by:
In which:
Function 1 is given by:
Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:
Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.
