Answer:

Step-by-step explanation:

You convert each fraction to have the same decimal to find the LCD of both denominators

4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common

You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4

One day last summer, Jim went kayaking on the Little Susitna River in Alaska. Paddling upstream against the current, he traveled

miv72 [106K]

Answer:

6.5 miles per hour

Step-by-step explanation:

At first, Jim was paddling against the current for 3 hours. Then, he paddled for 1 hour with the help of the current.

Let x be Jim's rate without the current and y be the rate of the current:

$(x-y)*3=12\\(x+y)*1=17$

By solving the linear system, we can find the rate of the current y:

$x=17-y\\(17-y-y)*3=12\\y=\frac{39}{6}\\y=6.5\ \frac{miles}{hour}$

The current has a rate of 6.5 miles per hour.
