Question 1143289
rate * time = distance.


rate = x for jaime without the wind.


t = time.


d = distance.


with the wind, the formula for jaime becomes (x + 5) * t = 42


against the wind, the formula for jaime becomes (x - 5) * t = 22


simlify both equations to get:


xt + 5t = 42
xt - 5t = 22


subtract second equation from the first to get:


10t = 20


solve for t to get:


t = 2


in the first equation, replace t with 2 to get (x + 5) * 2 = 42
in the second equation, replace t with 2 to get (x - 5) * 2 = 22


simplify both equationt to get:


2x + 10 = 42
2x - 10 = 22


solve for x in both equations to get:


x = 16


first original equation becomes (16 + 5) * 2 = 42
second original equation becomes (16 - 5) * 2 = 22


evaluate both equations to get:


42 = 42
22 = 22


this confirms both equations are correct when t = 2 and when x = 16.


your solution is that jaime rows at 16 miles per hour without any wind.
