the distance traveled is the same: 126 km. So, since distance = speed * time,
6(b-c) = 126
4.5(b+c) = 126
A boat travels from one port A to port B, travelling 126 km, upstream (against the current) at a uniform speed, and the trip takes 6 hours. On the way back (downstream), the trip only takes 4.5 hours.
Set up and solve a system of equations to find out the speed of the boat in still water and the speed of the current.
Let b = speed of boat km/h
Let c = speed of currrent in km/h

How would I solve this? I'm having trouble setting up equations.

Oh okay. Now I'll try to solve it and can you let me know if my answer will be right?
I got b=24.5 and c=3.5
Do you want to see my work as well?

nah - that's what I got.
Thank you so much! It's just that I have trouble making the equations. I can do it r simpler problems bit it gets difficult for me
Thank you!!!
Thank you!!!
