Answer:
Solution:
the boat's speed in still water: x
The speed with current: (x+3)
The speed against current: (x-3)
The equation is
3(x+3) = 4(x-3)
x = 21 mph
The distance = 3*(21+3)= 72 miles
I choose (A)
Step-by-step explanation:
Answer:
34;34;112
Step-by-step explanation:
It's a Isosceles triangle so the equation is
x+17=4x-34
x-4x=-35-17
-3x=-51
x=-51/-3
x=17
17+17=34
4.17-34=34
6.17+10=112
