A steamboat travels upstream, against the current, at a speed of 5 miles per hour. Later the steamboat travels downstream with the current, at a speed of 9 miles per hour. Choose the system of equations that can be solved to find the speed of the the steamboat, x, and the speed of the current, y.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
