A boat traveled downstream a distance of 136 mi and then came right back. If the speed of the current was 7 mph and the total trip took hours and 40 minutes, find the average speed of the boat relative to the water.

i have no clue at all sorry

step-by-step explanation:

idk

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
