On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Respuesta :

It is 40 because it gives you the even rate inbetween each of them

Answer:20

Step-by-step explanation:

Given Wind speed is 2 mile/hr

Let jamie speed be x km/hr

Also she covered 44 miles with wind in time t

[tex]44=\left ( x+2\right )t [/tex]

Against the wind

[tex]36=\left ( x-2\right )t[/tex]

divide the two equations

[tex]\frac{44}{36}=\frac{x+2}{x-2} [/tex]

11x-22=9x+18

x=20 miles/hr
