For brainiest and 50 points a ferry can travel 100 miles with the current in the same amount of time it takes to travel 60 miles against the current. if the speed of the ferry is 40 mph, what is the speed of the current?

The answer is x/10mph Hope I helped!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
