You say this is word problem but you didn't list it as one.
3x+3(x+10)=270
3(2x+10)=270
2x+10=90
2*(x+5)=90
x+5=45
x=40 kph
check
3*40+3*50=270
120+150=270
ok

I they are traveling in opposite directions
you can add their speeds and consider one
to be stationary and the other moving
Let = speed of the slower one
km

The slower boat's speed is 40 km/hr
check:
slower boat:

km
faster boat:

OK
